Struct CrateReleaseSource 

pub struct CrateReleaseSource { /* private fields */ }

The crates venue for one selector.

Implementations

impl CrateReleaseSource

pub fn new(selector: &str) -> Result<Self, RkError>

A source for selector — latest or an exact version — caching under the state root.

Errors

Returns RkError::Refusal when no state root can be located.

pub fn with_cache(selector: &str, cache: impl Into<PathBuf>) -> Self

A source caching under an explicit directory.

pub fn selector(&self) -> &str

The selector as given.

pub fn resolve(&self) -> Result<&Resolved, RkError>

Resolve the selector, fetch and verify the archive where the cache does not hold it, and answer with what happened. Idempotent: the second call answers from the first.

Errors

Returns a registry-unreachable refusal when the index or the archive cannot be fetched, a bundle-unverified refusal when the archive’s digest differs from the index checksum, and a usage error for a version the index does not list.
