Struct git_repository::Id

pub struct Id<'r> { /* private fields */ }

An ObjectId with access to a repository.

Implementations

impl<'repo> Id<'repo>

An object id infused with Easy.

pub fn object(&self) -> Result<Object<'repo>, Error>

Find the Object associated with this object id, and consider it an error if it doesn’t exist.

Note

There can only be one ObjectRef per Easy. To increase that limit, clone the Easy.

pub fn try_object(&self) -> Result<Option<Object<'repo>>, Error>

Try to find the Object associated with this object id, and return None if it’s not available locally.

Note

There can only be one ObjectRef per Easy. To increase that limit, clone the Easy.

pub fn shorten(&self) -> Result<Prefix, Error>

Turn this object id into a shortened id with a length in hex as configured by core.abbrev.

pub fn shorten_or_id(&self) -> Prefix

Turn this object id into a shortened id with a length in hex as configured by core.abbrev, or default to a prefix which equals our id in the unlikely error case.

impl<'repo> Id<'repo>

pub fn detach(self) -> ObjectId

Turn this instance into its bare ObjectId.

impl<'repo> Id<'repo>

pub fn ancestors(&self) -> Platform<'repo>

Obtain a platform for traversing ancestors of this commit.

Note that unless error_on_missing_commit() is enabled, which be default it is not, one will always see an empty iteration even if this id is not a commit, instead of an error. If this is undesirable, it’s best to check for the correct object type before creating an iterator.

Methods from Deref<Target = oid>

pub fn kind(&self) -> Kind

The kind of hash used for this Digest

pub fn first_byte(&self) -> u8

The first byte of the hash, commonly used to partition a set of Ids

pub fn as_bytes(&self) -> &[u8]

Interpret this object id as raw byte slice.

pub fn to_hex_with_len(&self, len: usize) -> HexDisplay<'_>

Return a type which can display itself in hexadecimal form with the len amount of characters.

pub fn to_hex(&self) -> HexDisplay<'_>

Return a type which displays this oid as hex in full.

pub fn hex_to_buf(&self, buf: &mut [u8]) -> usize

Write ourselves to the out in hexadecimal notation, returning the amount of written bytes.

Panics if the buffer isn’t big enough to hold twice as many bytes as the current binary size.

pub fn write_hex_to(&self, out: impl Write) -> Result<(), Error>

Write ourselves to out in hexadecimal notation

impl<'repo> PartialEq<Id<'repo>> for Id<'repo>

fn eq(&self, other: &Id<'repo>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
