Trait Implementations

impl<Qcx: Clone + QueryContext, K: Clone, V: Clone> Clone for QueryVTable<Qcx, K, V>where
    Qcx::DepKind: Clone,
    Qcx::DepContext: Clone,

fn clone(&self) -> QueryVTable<Qcx, K, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

    Qcx::DepKind: Copy,
    Qcx::DepContext: Copy,

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.
