Struct GlobalCache

Source 
pub struct GlobalCache<X: Cx> {
    map: HashMap<X::Input, CacheEntry<X>>,
}

Fields§

§map: HashMap<X::Input, CacheEntry<X>>

Implementations§

Source§

impl<X: Cx> GlobalCache<X>

Source

pub(super) fn insert( &mut self, cx: X, input: X::Input, origin_result: X::Result, dep_node: X::DepNodeIndex, additional_depth: usize, encountered_overflow: bool, nested_goals: NestedGoals<X>, )

Insert a final result into the global cache.

Source

pub(super) fn get<'a>( &'a self, cx: X, input: X::Input, available_depth: AvailableDepth, candidate_is_applicable: impl FnMut(&NestedGoals<X>) -> bool, ) -> Option<CacheData<'a, X>>

Try to fetch a cached result, checking the recursion limit and handling root goals of coinductive cycles.

If this returns Some the cache result can be used.
