Enum misc_utils::fs::Compression

pub enum Compression {
    Fastest,
    Default,
    Best,
    Numeric(u8),
}

Specify the compression level used.

There are three presets provided, Fastest, Default, and Best. They correspond to the settings in bzip2, gzip, and xz. Default corresponds to the value 6.

For bzip2 and gzip the Numeric values are mapped as follows:

Numeric	bzip2	gzip
0	<No compression>	Fastest
1	Fastest	Fastest
2	Fastest	Fastest
3	Fastest	Fastest
4	Default	Default
5	Default	Default
6	Default	Default
7	Best	Best
8	Best	Best
9	Best	Best
other values	Best	Best

For xz Numeric values in the range 0-9 (inclusive) are valid. The named variants are mapped to 0 for Fastest, 6 for Default, and 9 for Best.

Be aware that the result in compression ratio and time/memory consumption is highly dependent on the chosen filetype.

Variants

Fastest

Provide the fastest compression possible.

Default

Use a reasonable default, which does not consume too much CPU/memory.

Best

Provide the best compression possible.

Numeric(u8)

Fine-grained controll over the compression for the xz algorithm. Allowed values are 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 Copy for Compression

impl Eq for Compression

impl PartialEq for Compression

fn eq(&self, __arg_0: &Compression) -> bool

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

fn ne(&self, __arg_0: &Compression) -> bool

This method tests for !=.

impl Ord for Compression

fn cmp(&self, __arg_0: &Compression) -> Ordering

This method returns an Ordering between self and other.

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

🔬 This is a nightly-only experimental API. (ord_max_min)

Compares and returns the maximum of two values.

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

🔬 This is a nightly-only experimental API. (ord_max_min)

Compares and returns the minimum of two values.

impl PartialOrd for Compression

fn partial_cmp(&self, __arg_0: &Compression) -> Option<Ordering>

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

fn lt(&self, __arg_0: &Compression) -> bool

This method tests less than (for self and other) and is used by the < operator.
