Struct fixedbitset::FixedBitSet [] [src]

pub struct FixedBitSet { /* fields omitted */ }

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

The bit set has a fixed capacity in terms of enabling bits (and the capacity can grow using the grow method).

Methods

impl FixedBitSet
[src]

[src]

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

[src]

Grow capacity to bits, all new bits initialized to zero

[src]

Return the length of the FixedBitSet in bits.

[src]

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

Note: bits outside the capacity are always disabled.

Note: Also available with index syntax: bitset[bit].

[src]

Clear all bits.

[src]

Enable bit.

Panics if bit is out of bounds.

[src]

Enable bit, and return its previous value.

Panics if bit is out of bounds.

[src]

Panics if bit is out of bounds.

[src]

Copies boolean value from specified bit to the specified bit.

Panics if to is out of bounds.

[src]

Count the number of set bits in the given bit range.

Use .. to count the whole content of the bitset.

Panics if the range extends past the end of the bitset.

[src]

Sets every bit in the given range to the given state (enabled)

Use .. to toggle the whole bitset.

Panics if the range extends past the end of the bitset.

[src]

Enables every bit in the given range.

Use .. to make the whole bitset ones.

Panics if the range extends past the end of the bitset.

[src]

View the bitset as a slice of u32 blocks

[src]

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.

Important traits for Ones<'a>
[src]

Iterates over all enabled bits.

Iterator element is the index of the 1 bit, type usize.

impl Index<usize> for FixedBitSet
[src]
