Implementations

impl CompressionAlgorithm

pub fn supports_adaptive(&self) -> bool

Check if the algorithm supports adaptive compression

pub fn expected_compression_ratio(&self) -> f64

Get expected compression ratio for the algorithm

pub fn compression_speed(&self) -> f64

Get relative compression speed (higher = faster)

pub fn description(&self) -> &'static str

Get description of the algorithm

Trait Implementations

impl Clone for CompressionAlgorithm

fn clone(&self) -> CompressionAlgorithm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionAlgorithm

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

Formats the value using the given formatter.

impl Hash for CompressionAlgorithm

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 CompressionAlgorithm

fn eq(&self, other: &CompressionAlgorithm) -> 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.
