Update this package source, if it has state that needs to be updated.

Source

fn query(&self, package_req: &PackageReq) -> Result<Vec<Manifest>>

Query this package source for all of the packages that match this PackageReq.

Source

fn download_package(&self, package_id: &PackageId) -> Result<PackageContents>

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
