//! The purpose of of this crate is to abstract the user interface of `gix` (the command-line interface) from the actual implementation.//! That way, one day it's possible to provide alternative frontends, including user interfaces.//!//! ### What is `gix`?//!//! `gix` is a tool to aid developers of `gitoxide` run their code in real-world situations and to validate the `gix` API.//! This makes it more of a test-bed than a tool that could ever rival `git` in terms of feature-set.//!//! That said, `gix` may actively carve out a niche for itself where it sees the greatest benefits for users of `git`.//!//! ### This crate is internal - use `gix` instead.//!//! It's important to understand that this crate consider itself an implementation detail of the `gix` CLI and is not meant to be//! used for external consumption by means of `cargo` dependency. This is emphasized by there being no other documentation.//! There is also no intention of ever stabilizing this crate.//!//! If you want to get started with what powers `gix`, please take a look at the `gix` crate which provides all the building//! blocks to create any application, including a carbon-copy of `git` itself (at least aspirationally as not all capabilities are//! available in `gix` yet).//!//! For users of `gix`, this codebase might serve as elaborate example as most of not all of its APIs are used here.//!//! ## Feature Flags#![cfg_attr(    feature = "document-features",    cfg_attr(doc, doc = ::document_features::document_features!()))]#![cfg_attr(docsrs, feature(doc_cfg, doc_auto_cfg))]#![cfg_attr(feature = "async-client", allow(unused))]#![deny(rust_2018_idioms)]#![forbid(unsafe_code)] use std::str::FromStr; #[derive(Debug, Eq, PartialEq, Hash, Clone, Copy)]pub enum OutputFormat {    Human,    #[cfg(feature = "serde1")]    Json,} impl OutputFormat {    pub fn variants() -> &'static [&'static str] {        &[            "human",            #[cfg(feature = "serde1")]            "json",        ]    }} impl FromStr for OutputFormat {    type Err = String;     fn from_str(s: &str) -> Result<Self, Self::Err> {        let s_lc = s.to_ascii_lowercase();        Ok(match s_lc.as_str() {            "human" => OutputFormat::Human,            #[cfg(feature = "serde1")]            "json" => OutputFormat::Json,            _ => return Err(format!("Invalid output format: '{}'", s)),        })    }} pub mod net; pub mod commitgraph;#[cfg(feature = "estimate-hours")]pub mod hours;pub mod index;pub mod mailmap;#[cfg(feature = "organize")]pub mod organize;pub mod pack;pub mod repository; #[cfg(all(feature = "async-client", feature = "blocking-client"))]compile_error!("Cannot set both 'blocking-client' and 'async-client' features as they are mutually exclusive");
