# Struct cargo::sources::overlay::DependencyConfusionThreatOverlaySource

        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.

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<()>>

Attempts to find the packages that match a dependency request. Read more
source§

#### fn invalidate_cache(&mut self)

Ensure that the source is fully up-to-date for the current session on the next query.
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>

Starts the process to fetch a `Package` for the given `PackageId`. Read more
source§

#### fn finish_download( &mut self, pkg_id: PackageId, contents: Vec<u8>, ) -> CargoResult<Package>

Gives the source the downloaded `.crate` file. Read more
source§

#### fn fingerprint(&self, pkg: &Package) -> CargoResult<String>

source§

#### fn describe(&self) -> String

Describes this source in a human readable fashion, used for display in resolver error messages currently.
source§

#### fn add_to_yanked_whitelist(&mut self, pkgs: &[PackageId])

source§

#### fn is_yanked(&mut self, pkg: PackageId) -> Poll<CargoResult<bool>>

Query if a package is yanked. Only registry sources can mark packages as yanked. This ignores the yanked whitelist.
source§

source§

#### fn replaced_source_id(&self) -> SourceId

Returns the replaced `SourceId` corresponding to this source.
source§

#### fn query_vec( &mut self, dep: &Dependency, kind: QueryKind, ) -> Poll<CargoResult<Vec<IndexSummary>>>

Gathers the result from `Source::query` as a list of `IndexSummary` items when they become available.
source§

#### fn download_now( self: Box<Self>, package: PackageId, gctx: &GlobalContext, ) -> CargoResult<Package>
where Self: Sized,

Convenience method used to immediately fetch a `Package` for the given `PackageId`. Read more
source§

#### fn verify(&self, _pkg: PackageId) -> CargoResult<()>

If this source supports it, verifies the source of the package specified. Read more
source§

#### fn is_replaced(&self) -> bool

Returns whether a source is being replaced by another here. Read more
