Struct fixedbitset::FixedBitSet [] [src]

pub struct FixedBitSet {
    // some fields omitted
}

FixedBitSet is a simple fixed size set of bits that can be enabled (1 / true) or disabled (0 / false).

Methods

impl FixedBitSet
[src]

fn with_capacity(bits: usize) -> Self

Create a new FixedBitSet with a specific number of bits, all initially clear.

fn grow(&mut self, bits: usize)

Grow capacity to bits, all new bits initialized to zero

fn len(&self) -> usize

Return the length of the FixedBitSet in bits.

fn contains(&self, bit: usize) -> bool

Return true if the bit is enabled in the FixedBitSet, false otherwise.

Note: bits outside the capacity are always disabled.

fn clear(&mut self)

Clear all bits.

fn insert(&mut self, bit: usize)

Panics if bit is out of bounds.

fn set(&mut self, bit: usize, enabled: bool)

Panics if bit is out of bounds.

fn as_slice(&self) -> &[u32]

View the bitset as a slice of u32 blocks

fn as_mut_slice(&mut self) -> &mut [u32]

View the bitset as a mutable slice of u32 blocks. Writing past the bitlength in the last will cause contains to return potentially incorrect results for bits past the bitlength.
