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 Copy for CompressionStrategy

impl Eq for CompressionStrategy

impl Clone for CompressionStrategy

fn clone(&self) -> CompressionStrategy

Returns a copy of the value.

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