#![no_std]
+
+ 
//! This is a `no_std` crate which carries the struct [`Oid`] that represents
+ 
//! Git object identifiers. Currently, only SHA-1 digests are supported.
+ 
//!
+ 
//! ## Feature Flags
+ 
//!
+ 
//! The default features are `sha1` and `std`.
+ 
//!
+ 
//! ### `sha1`
+ 
//!
+ 
//! Enabled by default, since SHA-1 is commonly used. Currently, this feature is
+ 
//! also *required* to build the crate. In the future, after support for other
+ 
//! hashes is added, it might become possible to build the crate without support
+ 
//! for SHA-1.
+ 
//!
+ 
//! ### `std`
+ 
//!
+ 
//! [`Hash`]: ::doc_std::hash::Hash
+ 
//!
+ 
//! Enabled by default, since it is expected that most dependents will use the
+ 
//! standard library.
+ 
//!
+ 
//! Proves an implementation of [`Hash`].
+ 
//!
+ 
//! ### `git2`
+ 
//!
+ 
//! [`git2::Oid`]: ::git2::Oid
+ 
//!
+ 
//! Provides conversions to/from [`git2::Oid`].
+ 
//!
+ 
//! Note that as of version 0.19.0,
+ 
//!
+ 
//! ### `gix`
+ 
//!
+ 
//! [`ObjectId`]: ::gix_hash::ObjectId
+ 
//!
+ 
//! Provides conversions to/from [`ObjectId`].
+ 
//!
+ 
//! ### `schemars`
+ 
//!
+ 
//! [`JsonSchema`]: ::schemars::JsonSchema
+ 
//!
+ 
//! Provides an implementation of [`JsonSchema`].
+ 
//!
+ 
//! ### `serde`
+ 
//!
+ 
//! [`Serialize`]: ::serde::ser::Serialize
+ 
//! [`Deserialize`]: ::serde::de::Deserialize
+ 
//!
+ 
//! Provides implementations of [`Serialize`] and [`Deserialize`].
+ 
//!
+ 
//! ### `qcheck`
+ 
//!
+ 
//! [`qcheck::Arbitrary`]: ::qcheck::Arbitrary
+ 
//!
+ 
//! Provides an implementation of [`qcheck::Arbitrary`].
+ 
//!
+ 
//! ### `radicle-git-ref-format`
+ 
//!
+ 
//! [`radicle_git_ref_format::Component`]: ::radicle_git_ref_format::Component
+ 
//! [`radicle_git_ref_format::RefString`]: ::radicle_git_ref_format::RefString
+ 
//!
+ 
//! Conversion to [`radicle_git_ref_format::Component`]
+ 
//! (and also [`radicle_git_ref_format::RefString`]).
