Struct git_object::CommitRef

pub struct CommitRef<'a> {
    pub tree: &'a BStr,
    pub parents: SmallVec<[&'a BStr; 2]>,
    pub author: SignatureRef<'a>,
    pub committer: SignatureRef<'a>,
    pub encoding: Option<&'a BStr>,
    pub message: &'a BStr,
    pub extra_headers: Vec<(&'a BStr, Cow<'a, BStr>)>,
}

A git commit parsed using from_bytes().

A commit encapsulates information about a point in time at which the state of the repository is recorded, usually after a change which is documented in the commit message.

Fields

tree: &'a BStr

HEX hash of tree object we point to. Usually 40 bytes long.

Use tree() to obtain a decoded version of it.

parents: SmallVec<[&'a BStr; 2]>

HEX hash of each parent commit. Empty for first commit in repository.

author: SignatureRef<'a>

Who wrote this commit.

committer: SignatureRef<'a>

Who committed this commit.

This may be different from the author in case the author couldn’t write to the repository themselves and is commonly encountered with contributed commits.

encoding: Option<&'a BStr>

The name of the message encoding, otherwise UTF-8 should be assumed.

message: &'a BStr

The commit message documenting the change.

extra_headers: Vec<(&'a BStr, Cow<'a, BStr>)>

Extra header fields, in order of them being encountered, made accessible with the iterator returned by extra_headers().
