Struct git_object::CommitRefIter
source · pub struct CommitRefIter<'a> { /* private fields */ }
Expand description
Like CommitRef
, but as Iterator
to support (up to) entirely allocation free parsing.
It’s particularly useful to traverse the commit graph without ever allocating arrays for parents.
Implementations§
source§impl<'a> CommitRefIter<'a>
impl<'a> CommitRefIter<'a>
sourcepub fn from_bytes(data: &'a [u8]) -> CommitRefIter<'a> ⓘ
pub fn from_bytes(data: &'a [u8]) -> CommitRefIter<'a> ⓘ
Create a commit iterator from data.
sourcepub fn tree_id(&mut self) -> Result<ObjectId, Error>
pub fn tree_id(&mut self) -> Result<ObjectId, Error>
Returns the object id of this commits tree if it is the first function called and if there is no error in decoding the data.
Note that this method must only be called once or else will always return None while consuming a single token.
Errors are coerced into options, hiding whether there was an error or not. The caller should assume an error if they
call the method as intended. Such a squelched error cannot be recovered unless the objects data is retrieved and parsed again.
next()
.
sourcepub fn parent_ids(self) -> impl Iterator<Item = ObjectId> + 'a
pub fn parent_ids(self) -> impl Iterator<Item = ObjectId> + 'a
Return all parent_ids as iterator.
Parsing errors are ignored quietly.
sourcepub fn signatures(self) -> impl Iterator<Item = SignatureRef<'a>> + 'a
pub fn signatures(self) -> impl Iterator<Item = SignatureRef<'a>> + 'a
Returns all signatures, first the author, then the committer, if there is no decoding error.
Errors are coerced into options, hiding whether there was an error or not. The caller knows if there was an error or not if not exactly two signatures were iterable. Errors are not the common case - if an error needs to be detectable, use this instance as iterator.
sourcepub fn committer(self) -> Result<SignatureRef<'a>, Error>
pub fn committer(self) -> Result<SignatureRef<'a>, Error>
Returns the committer signature if there is no decoding error.
Returns the author signature if there is no decoding error.
It may contain white space surrounding it, and is exactly as parsed.
