Module checkout 

Borrowed file contents and bounded checkout traversal for caller-owned stores.

Sources supply hash-verified objects. A mutable source can evict its previous object on every lookup: traversal retains IDs and offsets, never object slices.

Structs

Entry

Owned metadata survives eviction of the parent tree.

Message

Exact commit-message location within a source object.

Root

Enums

Mode

Canonical Git modes; host permissions and submodule mounting are host policy.

Traits

ObjectSource

An immutable object view is valid until the next mutable source access.

Functions

lookup

Find one byte-string component in a previously validated tree. This checks framing and duplicate matches in one linear pass. Cache insertion should use object::Tree::parse_with_format for complete ordering/alias validation.

resolve_root

Peel at most max_tags annotated tags, check each declared target’s actual type and format, then resolve a commit’s tree (or a direct tree/blob ref). A tag cycle exhausts the explicit bound. No recursion or allocation is used.
