Required Methods

fn get_disjoint_entries<const N: usize>( &mut self, entries: [&K; N], default: impl FnMut(&K) -> V, ) -> Option<[&mut V; N]>

fn get_disjoint_two_entries( &mut self, left: &K, right: &K, left_default: impl FnMut(&K) -> V, right_default: impl FnMut(&V, &K) -> V, ) -> [Option<&mut V>; 2]

where V: Clone,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
