Enum 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.

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

Performs copy-assignment from source.

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 From<Compression> for CompressionOptions

fn from(compression: Compression) -> CompressionOptions

Converts to this type from the input type.

impl Hash for Compression

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 Ord for Compression

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

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

fn partial_cmp(&self, other: &Compression) -> 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.
