Struct BitSet 

pub struct BitSet { /* private fields */ }

Represents Java’s BitSet, a list of bits.

Implementations

impl BitSet

pub fn new(num_bits: usize) -> Self

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

Returns the bit at the given index.

Panics

Panics if the index is out of bounds. Use Self::get for a non-panicking version.

pub fn get(&self, index: usize) -> Option<bool>

pub fn clear(&mut self, range: Range<usize>)

Zeros the bits in the given range.

Panics

Panics if the range is invalid (start > end).

pub fn next_clear_bit(&self, from_index: usize) -> usize

Returns the index of the first bit that is set to false that occurs on or after the specified starting index.

pub fn set(&mut self, bit_index: usize)

Sets the bit at the given index to true.

Panics

Panics if the index is out of bounds. Check Self::len first if you need to avoid this.

pub fn iter_ones(&self) -> impl Iterator<Item = usize>

Returns the indices of all bits that are set to true.

pub fn len(&self) -> usize

Returns the maximum number of items that could be in this BitSet.

This will always be a multiple of 64.

pub fn is_empty(&self) -> bool

Returns true if the BitSet was created with a size of 0.

Equivalent to self.len() == 0.

Trait Implementations

impl AzaleaRead for BitSet

fn azalea_read(buf: &mut Cursor<&[u8]>) -> Result<Self, BufReadError>

impl AzaleaWrite for BitSet

fn azalea_write(&self, buf: &mut impl Write) -> Result<(), Error>

impl Clone for BitSet

fn clone(&self) -> BitSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BitSet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BitSet

fn default() -> BitSet

Returns the “default value” for a type.

impl From<Vec<u64>> for BitSet

fn from(data: Vec<u64>) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for BitSet

fn from(data: Vec<u8>) -> Self

Converts to this type from the input type.

impl Hash for BitSet

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for BitSet

fn eq(&self, other: &BitSet) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
