Implementations§

Source§

impl<'a> PackIndexView<'a>

Source

pub fn parse_v2_sha1(bytes: &'a [u8]) -> Result<Self>

Source

pub fn parse(bytes: &'a [u8], format: ObjectFormat) -> Result<Self>

Source

pub fn parse_without_checksum( bytes: &'a [u8], format: ObjectFormat, ) -> Result<Self>

Parse and validate the index layout without recomputing the trailing index checksum. The checksum stored in the file is still exposed via PackIndexView::index_checksum.

Source

pub fn parse_trusted_without_checksum( bytes: &'a [u8], format: ObjectFormat, ) -> Result<Self>

Parse a local/trusted pack index without recomputing the trailing index checksum or walking every entry for canonical-order validation.

This still validates the table layout and all lookup paths remain bounds-checked, but it avoids O(number-of-objects) startup validation for repository-owned .idx files in hot read paths.

pub fn count(&self) -> usize

pub fn fanout(&self) -> &[u32; 256]

pub fn find(&self, oid: &ObjectId) -> Option<PackIndexLookup>
