Struct bitvec::prelude::BitMut

pub struct BitMut<'a, C, T> where
    C: Cursor,
    T: 'a + BitStore,  { /* fields omitted */ }

Heavy-weight 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.

Trait Implementations

impl<'_, C, T> Deref for BitMut<'_, C, T> where
    C: Cursor,
    T: BitStore, 

type Target = bool

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'_, C, T> DerefMut for BitMut<'_, C, T> where
    C: Cursor,
    T: BitStore, 

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'_, C, T> Drop for BitMut<'_, C, T> where
    C: Cursor,
    T: BitStore, 

fn drop(&mut self)

Executes the destructor for this type.
