Implementations

impl PackIndex

pub fn write_v2_for_pack_sha1(pack_bytes: &[u8]) -> Result<PackIndexBuild>

pub fn write_v2_for_pack( pack_bytes: &[u8], format: ObjectFormat, ) -> Result<PackIndexBuild>

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

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

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

pub fn write_v2_sha1( entries: &[PackIndexEntry], pack_checksum: &ObjectId, ) -> Result<Vec<u8>>

pub fn write_v2( format: ObjectFormat, entries: &[PackIndexEntry], pack_checksum: &ObjectId, ) -> Result<Vec<u8>>

pub fn write_v1( format: ObjectFormat, entries: &[PackIndexEntry], pack_checksum: &ObjectId, ) -> Result<Vec<u8>>

Serialise a version-1 pack .idx: a 256-entry fanout, then for each object an inline 4-byte big-endian pack offset immediately followed by its object id (sorted by oid), then the pack checksum and a trailing index checksum. v1 has no CRC table and cannot represent offsets that do not fit in 32 bits.

Trait Implementations

impl Clone for PackIndex

fn clone(&self) -> PackIndex

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PackIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for PackIndex

impl PartialEq for PackIndex

fn eq(&self, other: &PackIndex) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
