Enum miniz_oxide::deflate::core::CompressionStrategy

#[repr(i32)]
pub enum CompressionStrategy {
    Default,
    Filtered,
    HuffmanOnly,
    RLE,
    Fixed,
}

Strategy setting for compression.

The non-default settings offer some special-case compression variants.

Variants

Default

Don’t use any of the special strategies.

Filtered

Only use matches that are at least 5 bytes long.

HuffmanOnly

Don’t look for matches, only huffman encode the literals.

RLE

Only look for matches with a distance of 1, i.e do run-length encoding only.

Fixed

Only use static/fixed blocks. (Blocks using the default huffman codes specified in the deflate specification.)

Trait Implementations

impl Clone for CompressionStrategy

fn clone(&self) -> CompressionStrategy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionStrategy

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

Formats the value using the given formatter.

impl Hash for CompressionStrategy

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<CompressionStrategy> for CompressionStrategy

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

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

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.
