Struct bitvec::slice::BitMut

source · [−]

pub struct BitMut<'a, O, T> where
    O: BitOrder,
    T: 'a + BitStore,  { /* private fields */ }

Expand description

Proxy referential type, equivalent to &mut bool.

This structure is three words wide, and cannot ever fit into the existing Rust language and library infrastructure in the way &BitSlice does. While &mut write references are themselves an affine type, with a guaranteed single point of destruction and no duplication, the language forbids writing finalization logic for them.

This means that a custom reference type which implements Deref and DerefMut to a location within the canonical handle, and on Drop writes the Deref location into referent memory, is impossible. Short of that, a C++-style thick reference-like type is as close as Rust will allow.
