-/// A Git commit's set of trailers that are left in the commit's
-/// message.
-///
-/// Trailers are key/value pairs in the last paragraph of a message,
-/// not including any patches or conflicts that may be present.
-///
-/// # Usage
-///
-/// To construct `Trailers`, you can use [`Trailers::parse`] or its
-/// `FromStr` implementation.
-///
-/// To iterate over the trailers, you can use [`Trailers::iter`].
-///
-/// To render the trailers to a `String`, you can use
-/// [`Trailers::to_string`] or its `Display` implementation (note that
-/// it will default to using `": "` as the separator.
-///
-/// # Examples
-///
-/// ```text
-/// Add new functionality
-///
-/// Making code better with new functionality.
-///
-/// X-Signed-Off-By: Alex Sellier
-/// X-Co-Authored-By: Fintan Halpenny

-/// An [`Index`] which can be shared between threads.
-///
-/// [`Shared`] assumes that:
-///
-/// * newer packs are likely to contain recent objects
-/// * lookups tend to favour recent objects
-/// * lookups tend to expect the object to be found (the object id is either
-///   pointed to by a ref, or linked to by an existing object)
-///
-/// Thus, it:
-///
-/// * orders indices found in `GIT_DIR/objects/pack` by modification time, and
-///   queries the more recent ones first
-/// * attempts to rescan `GIT_DIR/objects/pack` when an object id was _not_
-///   found (assuming that this is due to a compaction)
-///
-/// Unless a reload occurs, lookups are lock-free and mostly wait-free. Writes
-/// ([`Shared::push`], [`Shared::reload`]) are guarded by a [`Mutex`].
-// TODO: consecutive lookups also tend to resolve to the same pack, so we could
-// remember the index into the `im::Vector` where we found a match and look
-// there first. This is what libgit2 does, but the heuristic is not necessarily
-// true when `Shared` is shared across multiple concurrent link replication
-// tasks; per-namespace packs are independent pre-compaction.

-/// A fixed-size [`Cache`].
-///
-/// [`Fixed`] is essentially a very simple, fixed-capacity hashtable. When a
-/// pack (data-) file is requested via [`Cache::get`], the file is loaded
-/// (typically `mmap`ed) from disk if it is not already in the cache. Otherwise,
-/// a pointer to the already loaded file is returned. Old entries are replaced
-/// on an approximate LRU basis when the cache becomes full (this means that old
-/// entries are **not** evicted when there is still space).
-///
-/// The implementation is a somewhat dumbed-down version of JGit's
-/// `WindowCache`. The main differences are that the table buckets are of fixed
-/// size (`SLOTS`), instead of a linked list. This means that the cache does not
-/// allow to (temporarily) commit more entries than its nominal capacity.
-///
-/// Reading cached values is lock-free and mostly wait-free. Modifications are
-/// guarded by locks on individual buckets; if a cache miss occurs, multiple
-/// threads requesting the same entry will be blocked until one of them
-/// succeeded loading the data and updating the cache. Writers will _not_,
-/// however, contend with readers (unlike `RwLock`).
-///
-/// This favours usage patterns where different threads tend to request disjoint
-/// sets of packfiles, and of course their hashes colliding relatively
-/// infrequently.

-/// Threadsafe refdb with shareable `packed-refs` memory buffer.
-///
-/// Packed refs are a delicate business: they are written by an external
-/// process, [`git-pack-refs`], _or_ when a packed ref is deleted. It may also
-/// be that no `packed-refs` currently exist.
-///
-/// The only way we can be certain to operate on a consistent view of what is
-/// committed to disk is to check if the `packed-refs` file has changed since we
-/// last read it. This would be quite expensive to do for small operations.
-/// Thus, the caller is responsible for determining just how much they can
-/// afford to see possibly out-of-date data: the [`Refdb::snapshot`] method
-/// checks if the previously loaded `packed-refs` appear to be out-of-date, and
-/// reloads them if necessary. The resulting [`Snapshot`] contains a pointer to
-/// an immutable memory buffer of the packed refs which can be shared between
-/// threads, or cloned.
-///
-/// [`git-pack-refs`]: https://git-scm.com/docs/git-pack-refs
