Struct ZstdCompressionLevel

pub struct ZstdCompressionLevel(u8);

Compression level for zstd compression.

Tuple Fields

0: u8

Implementations

impl ZstdCompressionLevel

pub fn new(level: u8) -> Result<Self, Error>

Creates a new ZstdCompressionLevel from a u8.

The level must be in the range of ZstdCompressionLevel::min and ZstdCompressionLevel::max.

Errors

Returns an error if the value is not in the range of ZstdCompressionLevel::min and ZstdCompressionLevel::max.

pub const fn default_level() -> u8

Returns the default level (3) for ZstdCompressionLevel.

The default level adheres to the one selected by the zstd executable.

pub const fn min() -> u8

Returns the minimum allowed level (0) for ZstdCompressionLevel.

pub const fn max() -> u8

Returns the maximum allowed level (22) for ZstdCompressionLevel.

Trait Implementations

impl Clone for ZstdCompressionLevel

fn clone(&self) -> ZstdCompressionLevel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ZstdCompressionLevel

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

Formats the value using the given formatter.

impl Default for ZstdCompressionLevel

fn default() -> Self

Returns the default ZstdCompressionLevel.

Delegates to ZstdCompressionLevel::default_level for retrieving the default compression level.

impl Display for ZstdCompressionLevel

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

Formats the value using the given formatter.

impl From<&ZstdCompressionLevel> for i32

fn from(value: &ZstdCompressionLevel) -> Self

Converts to this type from the input type.

impl From<&ZstdCompressionLevel> for u32

fn from(value: &ZstdCompressionLevel) -> Self

Converts to this type from the input type.

impl PartialEq for ZstdCompressionLevel

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