Struct Compression 

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

The compression level to use for zlib-based streams, in the range from 0 (no compression) to 9 (best compression, slowest).

Note that git maps its configured level of -1 to the zlib default, which is level 6 and available as Compression::DEFAULT.

Implementations

impl Compression

pub const NONE: Compression

Do not compress at all, while still producing a valid zlib stream.

pub const BEST_SPEED: Compression

The fastest compression, with the lowest compression ratio, also known as level 1.

This is what git uses for loose objects unless configured otherwise with core.looseCompression.

pub const DEFAULT: Compression

The default compromise between speed and compression ratio, also known as level 6.

This is what git uses when writing packs unless configured otherwise with pack.compression.

pub const BEST: Compression

The best compression ratio at the expense of speed, also known as level 9.

pub fn new(level: i32) -> Option<Self>

Create a new instance from level if it is within the valid range from 0 to 9, inclusive.

pub fn level(&self) -> i32

Return the compression level as integer in the range from 0 to 9, inclusive.

Trait Implementations

impl Clone for Compression

fn clone(&self) -> Compression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Compression

impl Debug for Compression

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

Formats the value using the given formatter.

impl Default for Compression

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Compression

impl Hash for Compression

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 Ord for Compression

fn cmp(&self, other: &Compression) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Compression

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Compression

fn partial_cmp(&self, other: &Compression) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
