Struct Id 

pub struct Id<'r> {
    pub repo: &'r Repository,
    /* private fields */
}

An ObjectId with access to a repository.

Fields

repo: &'r Repository

The owning repository.

Implementations

impl<'repo> Id<'repo>

An object id infused with a Repository.

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 header(&self) -> Result<Header, Error>

Find the header associated with this object id, or an error if it doesn’t exist.

Use this method if there is no interest in the contents of the object, which generally is much faster to obtain.

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 try_header(&self) -> Result<Option<Header>, Error>

Find the header associated with this object id, or return None if it doesn’t exist.

Use this method if there is no interest in the contents of the object, which generally is much faster to obtain.

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.

Methods from Deref<Target = oid>

pub fn kind(&self) -> Kind

Available on crate feature excludes only.

The kind of hash used for this instance.

pub fn first_byte(&self) -> u8

Available on crate feature excludes only.

The first byte of the hash, commonly used to partition a set of object ids.

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

Available on crate feature excludes only.

Interpret this object id as raw byte slice.

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

Available on crate feature excludes only.

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

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

Available on crate feature excludes only.

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

pub fn hex_to_buf<'a>(&self, buf: &'a mut [u8]) -> &'a mut str

Available on crate feature excludes only.

Write ourselves to the out in hexadecimal notation, returning the hex-string ready for display.

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: &mut dyn Write) -> Result<(), Error>

Available on crate feature excludes only.

Write ourselves to out in hexadecimal notation.

pub fn is_null(&self) -> bool

Available on crate feature excludes only.

Returns true if this hash consists of all null bytes.

pub fn is_empty_blob(&self) -> bool

Available on crate feature excludes only.

Returns true if this hash is equal to an empty blob.

pub fn is_empty_tree(&self) -> bool

Available on crate feature excludes only.

Returns true if this hash is equal to an empty tree.

pub fn verify(&self, expected: &oid) -> Result<(), Error>

Available on crate feature excludes only.

Verify that self matches the expected object ID.

Returns an Error containing both object IDs if they differ.
