## Implementations§

source§

### impl ConflictCache

source

#### pub fn new() -> ConflictCache

source

#### pub fn find( &self, dep: &Dependency, is_active: &impl Fn(PackageId) -> Option<usize>, must_contain: Option<PackageId>, max_age: usize ) -> Option<&BTreeMap<PackageId, ConflictReason>>

source

#### pub fn find_conflicting( &self, cx: &Context, dep: &Dependency, must_contain: Option<PackageId> ) -> Option<&BTreeMap<PackageId, ConflictReason>>

Finds any known set of conflicts, if any, which are activated in `cx` and contain `PackageId` specified. If more than one are activated, then it will return one that will allow for the most jump-back.

source

#### pub fn conflicting( &self, cx: &Context, dep: &Dependency ) -> Option<&BTreeMap<PackageId, ConflictReason>>

source

#### pub fn insert( &mut self, dep: &Dependency, con: &BTreeMap<PackageId, ConflictReason> )

Adds to the cache a conflict of the form: `dep` is known to be unresolvable if all the `PackageId` entries are activated.

source

#### pub fn dependencies_conflicting_with( &self, pid: PackageId ) -> Option<&HashSet<Dependency>>

## Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain `repr(...)` attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
