pub struct DependencyConfusionThreatOverlaySource<'gctx> {
    local: Box<dyn Source + 'gctx>,
    remote: Box<dyn Source + 'gctx>,
}
Expand description

A Source that overlays one source over another, pretending that the packages available in the overlay are actually available in the other one.

This is a massive footgun and a terrible idea, so we do not (and never will) expose this publicly. However, it is useful for some very specific private things, like locally verifying a bunch of packages at a time before any of them have been published.

fn source_id(&self) -> SourceId

Returns the SourceId corresponding to this source.
source§

fn supports_checksums(&self) -> bool

Returns whether or not this source will return IndexSummary items with checksums listed.
source§

fn requires_precise(&self) -> bool

Returns whether or not this source will return IndexSummary items with the precise field in the SourceId listed.
source§

fn query( &mut self, dep: &Dependency, kind: QueryKind, f: &mut dyn FnMut(IndexSummary), ) -> Poll<CargoResult<()>>

source§

fn set_quiet(&mut self, quiet: bool)

If quiet, the source should not display any progress or status messages.
source§

fn download(&mut self, package: PackageId) -> CargoResult<MaybePackage>
