Methods

impl BitVector

pub fn new(num_bits: usize) -> BitVector

pub fn clear(&mut self)

pub fn count(&self) -> usize

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

pub fn insert(&mut self, bit: usize) -> bool

Returns true if the bit has changed.

Trait Implementations

impl Clone for BitVector

fn clone(&self) -> BitVector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BitVector

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

Formats the value using the given formatter.

impl PartialEq for BitVector

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

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

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

This method tests for !=.

impl FromIterator<bool> for BitVector

fn from_iter<I>(iter: I) -> BitVector where
    I: IntoIterator<Item = bool>, 

Creates a value from an iterator.
