Struct CratesIoResolver 

pub struct CratesIoResolver { /* private fields */ }

Resolve a selector against crates.io, or against the cache alone.

Implementations

impl CratesIoResolver

pub fn new(cache: &Utf8Path) -> Self

A resolver caching under cache.

pub const fn offline(self, offline: bool) -> Self

The same resolver, forbidden to reach the network.

pub fn with_index_root(self, root: &str) -> Self

The same resolver, reading a different index root.

A test serves the protocol from a local directory this way, so the suite exercises the resolver rather than a stub of it.

pub fn latest_version(&self) -> Result<Version, AppError>

The highest stable, non-yanked release the index serves.

One index read and nothing more: no archive is fetched. A cached answer cannot prove freshness, so this always reaches the index and --offline refuses it.

Errors

AppError::Refused where the network is refused or the index lists no stable release.

pub fn index_path(name: &str) -> String

The sparse index path for a crate name, as the protocol defines it.
