Enum deflate::Compression

pub enum Compression {
    Fast,
    Default,
    Best,
}

An enum describing the level of compression to be used by the encoder

Higher compression ratios will take longer to encode.

This is a simplified interface to specify a compression level.

See also CompressionOptions which provides for tweaking the settings more finely.

Variants

Fast

Fast minimal compression (CompressionOptions::fast()).

Default

Default level (CompressionOptions::default()).

Best

Higher compression level (CompressionOptions::high()).

Best in this context isn’t actually the highest possible level the encoder can do, but is meant to emulate the Best setting in the Flate2 library.

Trait Implementations

impl Clone for Compression

fn clone(&self) -> Compression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Compression

impl Debug for Compression

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

Formats the value using the given formatter.

impl Default for Compression

fn default() -> Compression

Returns the “default value” for a type.

impl Eq for Compression

impl From<Compression> for CompressionOptions

fn from(compression: Compression) -> CompressionOptions

Performs the conversion.

impl Hash for Compression

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for Compression

fn cmp(&self, other: &Compression) -> Ordering

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

impl PartialEq<Compression> for Compression

fn eq(&self, other: &Compression) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

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

This method tests for !=.

impl PartialOrd<Compression> for Compression

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

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

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

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

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

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