Enum Token 

pub enum Token<T> {
    Literal {
        symbol: T,
    },
    Reference {
        length: u32,
        distance: u32,
    },
}

An LZ77 token: either a literal symbol or a back-reference into the sliding window.

Variants

Literal

A single uncompressed symbol.

Fields

symbol: T

Reference

A back-reference copying length symbols from distance positions back in the window.

Fields

length: u32

distance: u32

Trait Implementations

impl<T: Clone> Clone for Token<T>

fn clone(&self) -> Token<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Token<T>

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

Formats the value using the given formatter.

impl<T> Default for Token<T>

where T: Default,

fn default() -> Self

Returns the “default value” for a type.

impl<T> Delta for Token<T>

where T: Delta,

fn delta(self, base: Self) -> Token<T>

Calculate the delta between self and base. Base must be less than or equal to self.

fn from_delta(base: Self, delta: Token<T>) -> Token<T>

Reconstruct the original value from base and delta.

impl<T: Hash> Hash for Token<T>

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<T: Ord> Ord for Token<T>

fn cmp(&self, other: &Token<T>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq for Token<T>

fn eq(&self, other: &Token<T>) -> 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.

impl<T: PartialOrd> PartialOrd for Token<T>

fn partial_cmp(&self, other: &Token<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<T> VarCode for Token<T>

where T: VarCode,

fn var_bit_len(&self) -> usize

fn var_write(&self, writer: &mut WriteBits<impl Write>) -> Result<()>

fn var_read(reader: &mut ReadBits<impl Read>) -> Result<Self>

impl<T: Copy> Copy for Token<T>

impl<T: Eq> Eq for Token<T>

impl<T> StructuralPartialEq for Token<T>
