pub fn new( registry_url: impl Into<String>, cache_dir: impl Into<PathBuf>, ) -> Result<Self>

Creates a registry using explicit source and cache values.

pub fn registry_url(&self) -> &str

Returns the configured registry URL, file URL, or filesystem path.

pub fn cache_dir(&self) -> &Path

Returns the root of the managed cache.

pub fn list(&self) -> Result<Vec<DatasetListing>>

Fetches the registry and reports whether each current version is cached.

pub fn download(&self, id: &str) -> Result<PathBuf>

Downloads, verifies, validates, and caches the current version of id.

An already-valid current installation is returned unchanged.

pub fn download_all(&self) -> Result<Vec<PathBuf>>

Downloads every registry entry sequentially and stops on the first error.

pub fn open(&self, id: &str) -> Result<Dataset>

Opens id, downloading it first when necessary.

A corrupt current installation is removed and installed once more.

pub fn clean(&self, id: &str) -> Result<bool>

Removes every cached version of id.

pub fn clean_all(&self) -> Result<usize>

Removes the complete marked managed cache and returns the version count.
