Struct RangeCoderState

pub struct RangeCoderState<Word, State: BitArray> { /* private fields */ }

Type of the internal state used by RangeEncoder<Word, State> and RangeDecoder<Word, State>. Relevant for Seeking.

Implementations

impl<Word: BitArray, State: BitArray> RangeCoderState<Word, State>

pub fn new(lower: State, range: State) -> Result<Self, ()>

pub fn lower(&self) -> State

Get the lower bound of the current range (inclusive)

pub fn range(&self) -> State::NonZero

Get the size of the current range

Trait Implementations

impl<Word: Clone, State: Clone + BitArray> Clone for RangeCoderState<Word, State>

where State::NonZero: Clone,

fn clone(&self) -> RangeCoderState<Word, State>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Word: Debug, State: Debug + BitArray> Debug for RangeCoderState<Word, State>

where State::NonZero: Debug,

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

Formats the value using the given formatter.

impl<Word: BitArray, State: BitArray> Default for RangeCoderState<Word, State>

fn default() -> Self

Returns the “default value” for a type.

impl<Word: Hash, State: Hash + BitArray> Hash for RangeCoderState<Word, State>

where State::NonZero: Hash,

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<Word: PartialEq, State: PartialEq + BitArray> PartialEq for RangeCoderState<Word, State>

where State::NonZero: PartialEq,

fn eq(&self, other: &RangeCoderState<Word, State>) -> 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.
