Struct Bitfield 

pub struct Bitfield { /* private fields */ }

One bit per piece: set when the piece is held and verified.

Implementations

impl Bitfield

pub fn new(len: u32) -> Self

All-clear bitfield for len pieces.

pub fn len(&self) -> u32

Number of pieces covered.

pub fn is_empty(&self) -> bool

True when it covers no pieces.

pub fn get(&self, i: u32) -> bool

pub fn set(&mut self, i: u32, v: bool)

Set or clear piece i (out-of-range indexes are ignored).

pub fn count(&self) -> u32

Number of set pieces.

pub fn is_complete(&self) -> bool

True when every piece is set.

pub fn missing(&self) -> impl Iterator<Item = u32> + '_

Indexes of pieces not set.
