    &self,
    tcx: CTX::DepContext,
    key: &K
) -> DepNode<CTX::DepKind> where
    K: DepNodeParams<CTX::DepContext>, 

pub(crate) fn compute(&self, tcx: CTX::DepContext, key: K) -> V

pub(crate) fn cache_on_disk(&self, tcx: CTX, key: &K, value: Option<&V>) -> bool

pub(crate) fn try_load_from_disk(
    &self,
    tcx: CTX,
    index: SerializedDepNodeIndex
) -> Option<V>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
