Enum Bzip2Level 

pub enum Bzip2Level {
    Fastest,
    Balanced,
    Best,
    Numeric(u32),
    Unknown,
}

Bzip2 compression level labels.

Variants

Fastest

Prefer fastest compression.

Balanced

Balance speed and compressed size.

Best

Prefer best compressed size.

Numeric(u32)

Caller-specified numeric level.

Unknown

Unknown or intentionally unspecified level.

Implementations

impl Bzip2Level

pub const fn as_str(self) -> &'static str

Returns a stable lowercase label.

pub const fn numeric(self) -> Option<u32>

Returns the numeric level when this is Bzip2Level::Numeric.

Trait Implementations

impl Clone for Bzip2Level

fn clone(&self) -> Bzip2Level

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bzip2Level

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

Formats the value using the given formatter.

impl Default for Bzip2Level

fn default() -> Bzip2Level

Returns the “default value” for a type.

impl Hash for Bzip2Level

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 Bzip2Level

fn cmp(&self, other: &Bzip2Level) -> 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 Bzip2Level

fn eq(&self, other: &Bzip2Level) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Bzip2Level

fn partial_cmp(&self, other: &Bzip2Level) -> 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.
