Trait BitSetLike

pub trait BitSetLike: Clone + Debug {
    // Required methods
    fn new_bitset(max: usize) -> Self;
    fn len(&self) -> usize;
    fn test(&self, ix: usize) -> bool;
    fn set(&mut self, ix: usize);
    fn clear(&mut self, ix: usize);

    // Provided method
    fn count(&self) -> usize { ... }
}

Trait for types which can be handled with BitSetStrategy.

Required Methods

fn new_bitset(max: usize) -> Self

Create a new value of Self with space for up to max bits, all initialised to zero.

fn len(&self) -> usize

Return an upper bound on the greatest bit set plus one.

fn test(&self, ix: usize) -> bool

Test whether the given bit is set.

fn set(&mut self, ix: usize)

Set the given bit.

fn clear(&mut self, ix: usize)

Clear the given bit.

Provided Methods

fn count(&self) -> usize

Return the number of bits set.

This has a default for backwards compatibility, which simply does a linear scan through the bits. Implementations are strongly encouraged to override this.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
