Enum miniz_oxide::deflate::CompressionLevel

#[repr(i32)]
pub enum CompressionLevel {
    NoCompression,
    BestSpeed,
    BestCompression,
    UberCompression,
    DefaultLevel,
    DefaultCompression,
}

How much processing the compressor should do to compress the data. NoCompression and Bestspeed have special meanings, the other levels determine the number of checks for matches in the hash chains and whether to use lazy or greedy parsing.

Variants

NoCompression

Don’t do any compression, only output uncompressed blocks.

BestSpeed

Fast compression. Uses a special compression routine that is optimized for speed.

BestCompression

Slow/high compression. Do a lot of checks to try to find good matches.

UberCompression

Even more checks, can be very slow.

DefaultLevel

Default compromise between speed and compression.

DefaultCompression

Use the default compression level.

Trait Implementations

impl Clone for CompressionLevel

fn clone(&self) -> CompressionLevel

Returns a copy of the value.

const 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 Hash for CompressionLevel

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq<CompressionLevel> for CompressionLevel

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
