Enum CompressionLevel

#[non_exhaustive]
pub enum CompressionLevel {
    Fastest,
    Best,
    Default,
    Precise(i32),
}

Available on crate features compression-br or compression-deflate or compression-gzip or compression-zstd or decompression-br or decompression-deflate or decompression-gzip or decompression-zstd only.

Level of compression data should be compressed with.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Fastest

Fastest quality of compression, usually produces bigger size.

Best

Best quality of compression, usually produces the smallest size.

Default

Default quality of compression defined by the selected compression algorithm.

Precise(i32)

Precise quality based on the underlying compression algorithms’ qualities.

The interpretation of this depends on the algorithm chosen and the specific implementation backing it.

Qualities are implicitly clamped to the algorithm’s maximum.

Trait Implementations

impl Clone for CompressionLevel

fn clone(&self) -> CompressionLevel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionLevel

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

Formats the value using the given formatter.

impl Default for CompressionLevel

fn default() -> CompressionLevel

Returns the “default value” for a type.

impl PartialEq for CompressionLevel

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