Struct git_pack::cache::lru::StaticLinkedList

pub struct StaticLinkedList<const SIZE: usize> { /* private fields */ }

Available on crate feature pack-cache-lru-static and (crate features pack-cache-lru-dynamic or pack-cache-lru-static) only.

A cache using a least-recently-used implementation capable of storing the SIZE most recent objects. The cache must be small as the search is ‘naive’ and the underlying data structure is a linked list. Values of 64 seem to improve performance.

Trait Implementations

impl<const SIZE: usize> DecodeEntry for StaticLinkedList<SIZE>

fn put(
    &mut self,
    pack_id: u32,
    offset: u64,
    data: &[u8],
    kind: Kind,
    compressed_size: usize
)

Store a fully decoded object at offset of kind with compressed_size and data in the cache.

fn get(
    &mut self,
    pack_id: u32,
    offset: u64,
    out: &mut Vec<u8>
) -> Option<(Kind, usize)>

Attempt to fetch the object at offset and store its decoded bytes in out, as previously stored with DecodeEntry::put(), and return its (object kind, decompressed_size)

impl<const SIZE: usize> Default for StaticLinkedList<SIZE>

fn default() -> Self

Returns the “default value” for a type.
