//! A module, responsible for managing the trust logic in Zed.
//!
//! It deals with multiple hosts, distinguished by [`RemoteHostLocation`].
//! Each [`crate::Project`] and `HeadlessProject` should call [`init_global`], if wants to establish the trust mechanism.
//! This will set up a [`gpui::Global`] with [`TrustedWorktrees`] entity that will persist, restore and allow querying for worktree trust.
//! It's also possible to subscribe on [`TrustedWorktreesEvent`] events of this entity to track trust changes dynamically.
//!
//! The implementation can synchronize trust information with the remote hosts: currently, WSL and SSH.
//! Docker and Collab remotes do not employ trust mechanism, as manage that themselves.
//!
//! Unless `trust_all_worktrees` auto trust is enabled, does not trust anything that was not persisted before.
//! When dealing with "restricted" and other related concepts in the API, it means all explicitly restricted, after any of the [`TrustedWorktreesStore::can_trust`] and [`TrustedWorktreesStore::can_trust_global`] calls.
//!
//! Zed does not consider invisible, `worktree.is_visible() == false` worktrees in Zed, as those are programmatically created inside Zed for internal needs, e.g. a tmp dir for `keymap_editor.rs` needs.
//!
//!
//! Path rust hierarchy.
//!
//! Zed has multiple layers of trust, based on the requests and [`PathTrust`] enum variants.
//! From the least to the most trusted level:
//!
//! * "single file worktree"
//!
//! After opening an empty Zed it's possible to open just a file, same as after opening a directory in Zed it's possible to open a file outside of this directory.
//! Usual scenario for both cases is opening Zed's settings.json file via `zed: open settings file` command: that starts a language server for a new file open, which originates from a newly created, single file worktree.
//!
//! Spawning a language server is potentially dangerous, and Zed needs to restrict that by default.
//! Each single file worktree requires a separate trust permission, unless a more global level is trusted.
//!
//! * "directory worktree"
//!
//! If a directory is open in Zed, it's a full worktree which may spawn multiple language servers associated with it.
//! Each such worktree requires a separate trust permission, so each separate directory worktree has to be trusted separately, unless a more global level is trusted.
//!
//! When a directory worktree is trusted and language servers are allowed to be downloaded and started, hence, "single file worktree" level of trust also.
//!
//! * "path override"
//!
//! To ease trusting multiple directory worktrees at once, it's possible to trust a parent directory of a certain directory worktree opened in Zed.
//! Trusting a directory means trusting all its subdirectories as well, including all current and potential directory worktrees.
