//! This crate provides the [`Repository`] abstraction which serves as a hub into all the functionality of git.//!//! It's powerful and won't sacrifice performance while still increasing convenience compared to using the sub-crates//! individually. Sometimes it may hide complexity under the assumption that the performance difference doesn't matter//! for all but the fewest tools out there, which would be using the underlying crates directly or file an issue.//!//! ## Example//!//! This is merely an introduction, for more see the respective [`Repository`] methods.//! ```//! # fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync>> {//! # mod doctest { include!(concat!(env!("CARGO_MANIFEST_DIR"), "/tests/doctest.rs")); }//! # let repo_dir = doctest::basic_repo_dir()?;//! # let repo = doctest::open_repo(repo_dir)?;//! let head = repo.head_commit()?;//!//! assert_eq!(repo.head_name()?.expect("born").shorten(), "main");//! assert_eq!(head.decode()?.message, "c2\n");//! assert_eq!(repo.head_tree_id()?, head.tree_id()?);//! # Ok(()) }//! ```//!//! ### The Trust Model//!//! It is very simple - based on the ownership of the repository compared to the user of the current process [Trust](sec::Trust)//! is assigned. This can be [overridden](open::Options::with()) as well. Further, git configuration files track their trust level//! per section based on and sensitive values like paths to executables or certain values will be skipped if they are from a source//! that isn't [fully](sec::Trust::Full) trusted.//!//! That way, data can safely be obtained without risking to execute untrusted executables.//!//! Note that it's possible to let `gix` act like `git` or `git2` by setting the [open::Options::bail_if_untrusted()] option.//!//! ### The prelude and extensions//!//! With `use git_repository::prelude::*` you should be ready to go as it pulls in various extension traits to make functionality//! available on objects that may use it.//!//! The method signatures are still complex and may require various arguments for configuration and cache control.//!//! Most extensions to existing objects provide an `obj_with_extension.attach(&repo).an_easier_version_of_a_method()` for simpler//! call signatures.//!//! ### `ThreadSafe` Mode//!//! By default, the [`Repository`] isn't `Sync` and thus can't be used in certain contexts which require the `Sync` trait.//!//! To help with this, convert it with [`Repository::into_sync()`] into a [`ThreadSafeRepository`].//!//! ### Object-Access Performance//!//! Accessing objects quickly is the bread-and-butter of working with git, right after accessing references. Hence it's vital//! to understand which cache levels exist and how to leverage them.//!//! When accessing an object, the first cache that's queried is a  memory-capped LRU object cache, mapping their id to data and kind.//! It has to be specifically enabled on a [`Repository`].//! On miss, the object is looked up and if a pack is hit, there is a small fixed-size cache for delta-base objects.//!//! In scenarios where the same objects are accessed multiple times, the object cache can be useful and is to be configured specifically//! using the [`Repository::object_cache_size()`] method.//!//! Use the `cache-efficiency-debug` cargo feature to learn how efficient the cache actually is - it's easy to end up with lowered//! performance if the cache is not hit in 50% of the time.//!//! ### Terminology//!//! #### `WorkingTree` and `WorkTree`//!//! When reading the documentation of the canonical gix-worktree program one gets the impression work tree and working tree are used//! interchangeably. We use the term _work tree_ only and try to do so consistently as its shorter and assumed to be the same.//!//! ### Plumbing Crates//!//! To make using  _sub-crates_ and their types easier, these are re-exported into the root of this crate. Here we list how to access nested plumbing//! crates which are otherwise harder to discover://!//! **`git_repository::`**//! * [`odb`]//!   * [`pack`][odb::pack]//! * [`protocol`]//!   * [`transport`][protocol::transport]//!     * [`packetline`][protocol::transport::packetline]//!//! ### `libgit2` API to `gix`//!//! This doc-aliases are used to help finding methods under a possibly changed name. Just search in the docs.//! Entering `git2` into the search field will also surface all methods with such annotations.//!//! What follows is a list of methods you might be missing, along with workarounds if available.//! * [`git2::Repository::open_bare()`](https://docs.rs/git2/*/git2/struct.Repository.html#method.open_bare) ➡ ❌ - use [`open()`] and discard if it is not bare.//! * [`git2::build::CheckoutBuilder::disable_filters()`](https://docs.rs/git2/*/git2/build/struct.CheckoutBuilder.html#method.disable_filters) ➡ ❌ *(filters are always applied during checkouts)*//! * [`git2::Repository::submodule_status()`](https://docs.rs/git2/*/git2/struct.Repository.html#method.submodule_status) ➡ [`Submodule::state()`] - status provides more information and conveniences though, and an actual worktree status isn't performed.//!//! #### Integrity checks//!//! `git2` by default performs integrity checks via [`strict_hash_verification()`](https://docs.rs/git2/latest/git2/opts/fn.strict_hash_verification.html) and//! [`strict_object_creation`](https://docs.rs/git2/latest/git2/opts/fn.strict_object_creation.html) which `gitoxide` *currently* **does not have**.//!//! ### Feature Flags#![cfg_attr(    all(doc, feature = "document-features"),    doc = ::document_features::document_features!())]#![cfg_attr(all(doc, feature = "document-features"), feature(doc_cfg))]#![deny(missing_docs, unsafe_code)]#![allow(clippy::result_large_err)] // Re-exports to make this a potential one-stop shop crate avoiding people from having to reference various crates themselves.// This also means that their major version changes affect our major version, but that's alright as we directly expose their// APIs/instances anyway.pub use gix_actor as actor;#[cfg(feature = "attributes")]pub use gix_attributes as attrs;#[cfg(feature = "blame")]pub use gix_blame as blame;#[cfg(feature = "command")]pub use gix_command as command;pub use gix_commitgraph as commitgraph;#[cfg(feature = "credentials")]pub use gix_credentials as credentials;pub use gix_date as date;#[cfg(feature = "dirwalk")]pub use gix_dir as dir;pub use gix_error as error;pub use gix_features as features;use gix_features::threading::OwnShared;pub use gix_features::{    parallel,    progress::{Count, DynNestedProgress, NestedProgress, Progress},    threading,};pub use gix_fs as fs;pub use gix_glob as glob;pub use gix_hash as hash;pub use gix_hashtable as hashtable;#[cfg(feature = "excludes")]pub use gix_ignore as ignore;#[doc(inline)]#[cfg(feature = "index")]pub use gix_index as index;pub use gix_lock as lock;#[cfg(feature = "credentials")]pub use gix_negotiate as negotiate;pub use gix_object as objs;pub use gix_object::bstr;pub use gix_odb as odb;#[cfg(feature = "credentials")]pub use gix_prompt as prompt;pub use gix_protocol as protocol;pub use gix_ref as refs;pub use gix_refspec as refspec;pub use gix_revwalk as revwalk;pub use gix_sec as sec;pub use gix_tempfile as tempfile;pub use gix_trace as trace;pub use gix_traverse as traverse;pub use gix_url as url;#[doc(inline)]pub use gix_url::Url;pub use gix_utils as utils;pub use gix_validate as validate;pub use gix_zlib as zlib;pub use hash::{ObjectId, oid}; pub use gix_error::{Error, Exn}; pub mod interrupt; mod ext;///pub mod prelude; #[cfg(feature = "excludes")]mod attribute_stack; ///pub mod path; /// The standard type for a store to handle git references.pub type RefStore = gix_ref::file::Store;/// A handle for finding objects in an object database, abstracting away caches for thread-local use.pub type OdbHandle = gix_odb::memory::Proxy<gix_odb::Handle>;/// A handle for finding objects in an object database, abstracting away caches for moving across threads.pub type OdbHandleArc = gix_odb::memory::Proxy<gix_odb::HandleArc>; /// A way to access git configurationpub(crate) type Config = OwnShared<gix_config::File>; mod types;#[cfg(any(feature = "excludes", feature = "attributes"))]pub use types::AttributeStack;pub use types::{    Blob, Commit, Head, Id, Object, ObjectDetached, Reference, Remote, Repository, Tag, ThreadSafeRepository, Tree,    Worktree,};#[cfg(feature = "attributes")]pub use types::{Pathspec, PathspecDetached, Submodule}; ///pub mod clone;pub mod commit;///#[cfg(feature = "dirwalk")]pub mod dirwalk;pub mod head;pub mod id;pub mod object;#[cfg(feature = "attributes")]pub mod pathspec;pub mod reference;pub mod repository;#[cfg(feature = "attributes")]pub mod submodule;pub mod tag;#[cfg(any(feature = "dirwalk", feature = "status"))]pub(crate) mod util; ///pub mod progress;///pub mod push; ///pub mod diff; ///#[cfg(feature = "merge")]pub mod merge; /// Try to open a git repository in `directory` and search upwards through its parents until one is found,/// using default trust options which matters in case the found repository isn't owned by the current user.////// For details, see [`ThreadSafeRepository::discover()`].////// # Note////// **The discovered repository might not be suitable for any operation that requires authentication with remotes**/// as it doesn't see the relevant git configuration.////// To achieve that, one has to [enable `git_binary` configuration](https://github.com/GitoxideLabs/gitoxide/blob/9723e1addf52cc336d59322de039ea0537cdca36/src/plumbing/main.rs#L86)/// in the open-options and use [`ThreadSafeRepository::discover_opts()`] instead.
