Struct ObjectHasher 

pub struct ObjectHasher<'repo, R: Repository + ?Sized> { /* private fields */ }

Resumable Git object hashing. Retain this value between step calls; it owns a cursor and hash state but no scratch. size_of::<ObjectHasher<'_, R>>() gives the exact inline state budget for a target. IDs include kind and size.

Implementations

impl<'repo, R: Repository + ?Sized> ObjectHasher<'repo, R>

pub fn new(repository: &'repo R, index: usize) -> Result<Self>

pub fn position(&self) -> u64

pub fn step(&mut self, scratch: &mut [u8]) -> Result<Option<ObjectId>>

Perform at most one provider read. None means more steps are needed; Some(id) means the declared body is complete. Completed calls repeat the same ID without rereading. Read errors leave the hash unchanged.

pub fn finish(self, scratch: &mut [u8]) -> Result<ObjectId>

Hash the remaining body synchronously using only the supplied scratch.
