Struct ConflictCache

pub(super) struct ConflictCache {
    con_from_dep: FxHashMap<Dependency, ConflictStoreTrie>,
    dep_from_pid: FxHashMap<PackageId, FxHashSet<Dependency>>,
}

Fields

con_from_dep: FxHashMap<Dependency, ConflictStoreTrie>

dep_from_pid: FxHashMap<PackageId, FxHashSet<Dependency>>

Implementations

impl ConflictCache

pub fn new() -> ConflictCache

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

pub fn find_conflicting( &self, cx: &ResolverContext, 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.

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

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.

pub fn dependencies_conflicting_with( &self, pid: PackageId, ) -> Option<&FxHashSet<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.
