Trait Implementations

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

    CTX::DepKind: Copy,
    CTX::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.
