Struct fixedbitset::FixedBitSet

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

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.

Trait Implementations

impl Hash for FixedBitSet

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher

Feeds a slice of this type into the state provided.

impl Ord for FixedBitSet

fn cmp(&self, __arg_0: &FixedBitSet) -> Ordering

This method returns an Ordering between self and other.

impl PartialOrd for FixedBitSet

fn partial_cmp(&self, __arg_0: &FixedBitSet) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &FixedBitSet) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &FixedBitSet) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &FixedBitSet) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &FixedBitSet) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Eq for FixedBitSet

impl PartialEq for FixedBitSet

fn eq(&self, __arg_0: &FixedBitSet) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &FixedBitSet) -> bool

This method tests for !=.

impl Debug for FixedBitSet

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for FixedBitSet

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Index<usize> for FixedBitSet

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

type Output = bool

The returned type after indexing

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

The method for the indexing (Foo[Bar]) operation
