Implementations§

Source§

impl MultiPackIndex

Source

pub fn write( format: ObjectFormat, version: u8, pack_names: &[String], objects: &[MultiPackIndexEntry], ) -> Result<Vec<u8>>

Source

pub fn write_with_reverse_index( format: ObjectFormat, version: u8, pack_names: &[String], objects: &[MultiPackIndexEntry], preferred_pack: Option<u32>, ) -> Result<Vec<u8>>

Like MultiPackIndex::write, but when preferred_pack is Some, additionally emits the RIDX chunk: the object order a multi-pack .bitmap numbers its bits in (“pseudo-pack order” — every object of the preferred pack first, then the rest by pack id, each pack’s slice in offset order), stored as one u32 midx position per object.

preferred_pack is the pack-int-id receiving pseudo-pack priority; it must be in range.

Source

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

Source

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