Expand description
A Source finds and downloads remote packages based on names and versions.
Required Methods
sourcefn supports_checksums(&self) -> bool
fn supports_checksums(&self) -> bool
Returns whether or not this source will return summaries with checksums listed.
sourcefn requires_precise(&self) -> bool
fn requires_precise(&self) -> bool
Returns whether or not this source will return summaries with
the precise
field in the source id listed.
sourcefn query(
&mut self,
dep: &Dependency,
f: &mut dyn FnMut(Summary)
) -> CargoResult<()>
fn query(
&mut self,
dep: &Dependency,
f: &mut dyn FnMut(Summary)
) -> CargoResult<()>
Attempt to find the packages that match a dependency request.
sourcefn fuzzy_query(
&mut self,
dep: &Dependency,
f: &mut dyn FnMut(Summary)
) -> CargoResult<()>
fn fuzzy_query(
&mut self,
dep: &Dependency,
f: &mut dyn FnMut(Summary)
) -> CargoResult<()>
Attempt to find the packages that are close to a dependency request.
Each source gets to define what close
means for it.
path/git sources may return all dependencies that are at that uri.
where as an Index source may return dependencies that have the same canonicalization.
sourcefn update(&mut self) -> CargoResult<()>
fn update(&mut self) -> CargoResult<()>
The update method performs any network operations required to get the entire list of all names, versions and dependencies of packages managed by the Source.
sourcefn download(&mut self, package: &PackageId) -> CargoResult<MaybePackage>
fn download(&mut self, package: &PackageId) -> CargoResult<MaybePackage>
The download method fetches the full package for each name and version specified.
fn finish_download(
&mut self,
package: &PackageId,
contents: Vec<u8>
) -> CargoResult<Package>
sourcefn fingerprint(&self, pkg: &Package) -> CargoResult<String>
fn fingerprint(&self, pkg: &Package) -> CargoResult<String>
Generates a unique string which represents the fingerprint of the current state of the source.
This fingerprint is used to determine the “fresheness” of the source later on. It must be guaranteed that the fingerprint of a source is constant if and only if the output product will remain constant.
The pkg
argument is the package which this fingerprint should only be
interested in for when this source may contain multiple packages.
Provided Methods
sourcefn replaced_source_id(&self) -> &SourceId
fn replaced_source_id(&self) -> &SourceId
Returns the replaced SourceId
corresponding to this source
fn query_vec(&mut self, dep: &Dependency) -> CargoResult<Vec<Summary>>
sourcefn verify(&self, _pkg: &PackageId) -> CargoResult<()>
fn verify(&self, _pkg: &PackageId) -> CargoResult<()>
If this source supports it, verifies the source of the package specified.
Note that the source may also have performed other checksum-based
verification during the download
step, but this is intended to be run
just before a crate is compiled so it may perform more expensive checks
which may not be cacheable.
sourcefn is_replaced(&self) -> bool
fn is_replaced(&self) -> bool
Returns whether a source is being replaced by another here
