Struct guppy::graph::DependsCache [−][src]
An optional cache used to speed up depends_on
queries.
Created with PackageGraph::new_depends_cache()
.
Implementations
impl<'g> DependsCache<'g>
[src]
pub fn new(package_graph: &'g PackageGraph) -> Self
[src]
Creates a new cache for depends_on
queries for this package graph.
This holds a shared reference to the package graph. This is to ensure that the cache is invalidated if the package graph is mutated.
pub fn depends_on(
&mut self,
package_a: &PackageId,
package_b: &PackageId
) -> Result<bool, Error>
[src]
&mut self,
package_a: &PackageId,
package_b: &PackageId
) -> Result<bool, Error>
Returns true if package_a
depends (directly or indirectly) on package_b
.
In other words, this returns true if package_b
is a (possibly transitive) dependency of
package_a
.
