Implementations

impl CompressionKind

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of CompressionKind.

pub fn from_i32(value: i32) -> Option<CompressionKind>

Converts an i32 to a CompressionKind, or None if value is not a valid variant.

Trait Implementations

impl Clone for CompressionKind

fn clone(&self) -> CompressionKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionKind

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

Formats the value using the given formatter.

impl Default for CompressionKind

fn default() -> CompressionKind

Returns the “default value” for a type.

impl From<CompressionKind> for i32

fn from(value: CompressionKind) -> i32

Converts to this type from the input type.

impl Hash for CompressionKind

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,

impl Ord for CompressionKind

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<CompressionKind> for CompressionKind

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