Module bitmap 

Pack and commit reachability bitmaps.

Structs

BitmapIndex

Memory-mapped pack or MIDX reachability bitmap (Git BITM v1).

BitmapIndexCache

Repository-scoped cache slot for BitmapIndex::open.

BitmapWalkUnsupported

Bitmap walk could not run (unsupported filter or shallow repo); use a non-bitmap walk instead.

CommitReachabilityBitmap

Decoded reachability set for one commit (bits index pack/MIDX object positions).

MidxBitmapWriter

Writes .bitmap sidecars for multi-pack-index files (MIDX checksum in header).

PackBitmapWriteOptions

Options controlling pack bitmap generation (caller-supplied; not read from the environment).

PackBitmapWriter

Writes .bitmap sidecars for pack indexes produced by all-into-one repacks.

ReachabilityQuery

Query parameters for a bitmap reachability walk.

ReachableSet

Reachable objects from a ReachabilityQuery: in-index bits plus out-of-namespace oids.

TypeBitmap

Borrowed type filter bitmap (commits, trees, blobs, or tags).

Enums

BitmapError

Failure mode when a .bitmap sidecar cannot be used.

BitmapWalkError

Errors during a bitmap reachability walk.

PackBitmapWriteError

Failure while writing a pack reachability bitmap.

Functions

bitmap_filter_supported

Returns true when filter can be applied via type bitmaps (mirrors Git can_filter_bitmap).
