Expand description
Something that packages can be downloaded from.
Required Methods§
sourcefn query<'life0, 'life1, 'async_trait>(
&'life0 self,
package: &'life1 PackageSource,
) -> Pin<Box<dyn Future<Output = Result<Vec<PackageSummary>, QueryError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
fn query<'life0, 'life1, 'async_trait>(
&'life0 self,
package: &'life1 PackageSource,
) -> Pin<Box<dyn Future<Output = Result<Vec<PackageSummary>, QueryError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
Ask this source which packages would satisfy a particular
Dependency
constraint.
§Assumptions
If this method returns a successful result, it is guaranteed that there
will be at least one PackageSummary
, otherwise implementations
should return QueryError::NotFound
or QueryError::NoMatches
.
Provided Methods§
sourcefn latest<'life0, 'life1, 'async_trait>(
&'life0 self,
pkg: &'life1 PackageSource,
) -> Pin<Box<dyn Future<Output = Result<PackageSummary, QueryError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
fn latest<'life0, 'life1, 'async_trait>(
&'life0 self,
pkg: &'life1 PackageSource,
) -> Pin<Box<dyn Future<Output = Result<PackageSummary, QueryError>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
'life1: 'async_trait,
Run Source::query()
and get the PackageSummary
for the latest
version.
