Type Alias SelectionCache

pub type SelectionCache<'tcx> = Cache<(ParamEnv<'tcx>, TraitPredicate<'tcx>), SelectionResult<'tcx, SelectionCandidate<'tcx>>>;

Aliased Type

struct SelectionCache<'tcx> { /* private fields */ }

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.

Implementations

impl<Key, Value> Cache<Key, Value>

pub fn clear(&self)

Actually frees the underlying memory in contrast to what stdlib containers do on clear

impl<Key, Value> Cache<Key, Value>

where Key: Eq + Hash, Value: Clone,

pub fn get<Tcx>(&self, key: &Key, tcx: Tcx) -> Option<Value>

where Tcx: DepContext,

pub fn insert(&self, key: Key, dep_node: DepNodeIndex, value: Value)

Trait Implementations

impl<Key, Value> Clone for Cache<Key, Value>

where Key: Clone, Value: Clone,

fn clone(&self) -> Cache<Key, Value>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Key, Value> Default for Cache<Key, Value>

fn default() -> Cache<Key, Value>

Returns the “default value” for a type.
