Struct flate2::Compression

pub struct Compression(/* private fields */);

When compressing data, the compression level can be specified by a value in this enum.

Implementations

impl Compression

pub fn new(level: u32) -> Compression

Creates a new description of the compression level with an explicitly specified integer.

The integer here is typically on a scale of 0-9 where 0 means “no compression” and 9 means “take as long as you’d like”.

pub fn none() -> Compression

No compression is to be performed, this may actually inflate data slightly when encoding.

pub fn fast() -> Compression

Optimize for the best speed of encoding.

pub fn best() -> Compression

Optimize for the size of data being encoded.

pub fn level(&self) -> u32

Returns an integer representing the compression level, typically on a scale of 0-9

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 PartialEq for Compression

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

impl Copy for Compression

impl Eq for Compression

impl StructuralPartialEq for Compression
