Struct ObjectReader 

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

A cursor over a stable repository object. It contains only a repository reference, index, metadata, and offset, with no body buffer or allocation. Use core::mem::size_of::<ObjectReader<'_, R>>() for the host’s state budget.

Implementations

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

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

pub fn info(&self) -> ObjectInfo

pub fn object_format(&self) -> ObjectFormat

pub fn position(&self) -> u64

pub fn remaining(&self) -> u64

pub fn seek(&mut self, position: u64) -> Result<()>

Resume or reread at an offset within the body, including EOF.

pub fn read(&mut self, storage: &mut [u8]) -> Result<usize>

Read one bounded chunk. Empty scratch is an error unless at EOF. Early EOF or a provider reporting more bytes than requested is InvalidObject. On error the position is unchanged, so a stable provider can be retried.
