Struct ByteSet 

pub struct ByteSet(/* private fields */);

A set of bytes, stored as a 256 bits bitmap. Useful if you want to write your own prefilter.

Implementations

impl ByteSet

pub fn insert(&mut self, byte: u8)

Adds a byte to the set

pub fn is_empty(&self) -> bool

Whether the set contains any bytes at all

pub fn contains(&self, byte: u8) -> bool

Whether the set contains that byte

pub fn union(&mut self, other: &Self)

Adds every byte of other to the set

pub fn intersection(&mut self, other: &Self)

Removes every byte not in other

pub fn is_subset(&self, other: &Self) -> bool

Returns whether the current byte set is a subset of the given one

pub fn iter(&self) -> impl Iterator<Item = u8> + '_

Iterates over the bytes in the set, in ascending order

pub fn words(&self) -> &[u64; 4]

The underlying bitmap.

pub const fn from_words(words: [u64; 4]) -> Self

Builds a set from a bitmap returned by ByteSet::words.
