Module fetch 

Dependency acquisition layer for the Soroban DevKit (sdkt), .

Provides a reusable abstraction for fetching package dependencies into a deterministic local cache. This milestone implements Git acquisition (via the git CLI) and a path (local) source that needs no fetch. The DependencyFetcher trait is the seam: a future registry source can be added as another implementation without touching callers.

Design goals:

• No network during tests — tests use on-the-fly local git repositories.
• Deterministic cache layout: <cache_root>/git/<stable-hash>/ so repeated fetches are idempotent.
• No authentication helpers, no registry. The Git backend shells out to the system git binary (assumed present, like cargo/rustc).
• Never builds — fetch only materializes source; building is the caller’s responsibility.

Structs

FetchOutcome

The outcome of a fetch operation for one dependency.

GitFetcher

Git-backed dependency fetcher.

PathResolver

A no-network “fetcher” for local path dependencies: it only validates that the path exists and returns it unchanged.

Enums

FetchError

Errors raised while acquiring a dependency.

Traits

DependencyFetcher

A source a dependency can be acquired from.

Functions

git_bin

Resolve the git executable.

git_cache_key

Stable, filesystem-safe cache key for a Git dependency.
