toolchain: &str,
host: Option<&str>,
source: &impl Source,
) -> Result<Catalog>Expand description

Reads metadata/sidecars only and writes no files. Availability does not establish native execution or SDK availability.
ยงErrors
Refuses unsupported selectors, malformed/hash-invalid metadata, unknown hosts or upstream transport/size failures.
