Struct cargo::sources::replaced::ReplacedSource

pub struct ReplacedSource<'gctx> { /* private fields */ }

A source that replaces one source with the other. This manages the source replacement feature.

The implementation is merely redirecting from the original to the replacement.

Implementations

impl<'gctx> ReplacedSource<'gctx>

pub fn new( to_replace: SourceId, replace_with: SourceId, src: Box<dyn Source + 'gctx> ) -> ReplacedSource<'gctx>

Creates a replaced source.

The src argument is the new replacement source.

Trait Implementations

impl<'gctx> Source for ReplacedSource<'gctx>

fn source_id(&self) -> SourceId

Returns the SourceId corresponding to this source.

fn replaced_source_id(&self) -> SourceId

Returns the replaced SourceId corresponding to this source.

fn supports_checksums(&self) -> bool

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

fn requires_precise(&self) -> bool

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

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.

fn invalidate_cache(&mut self)

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

fn set_quiet(&mut self, quiet: bool)

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

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

Starts the process to fetch a Package for the given PackageId.

fn finish_download( &mut self, id: PackageId, data: Vec<u8> ) -> CargoResult<Package>

Gives the source the downloaded .crate file.

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

Generates a unique string which represents the fingerprint of the current state of the source.

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

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

fn describe(&self) -> String

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

fn is_replaced(&self) -> bool

Returns whether a source is being replaced by another here.

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

Add a number of crates that should be whitelisted for showing up during queries, even if they are yanked. Currently only applies to registry sources.

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.

fn block_until_ready(&mut self) -> CargoResult<()>

Block until all outstanding Poll::Pending requests are Poll::Ready.

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.

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.
