Struct ZstdConfig

#[non_exhaustive]
pub struct ZstdConfig {
    pub level: Option<NonZeroU8>,
}

Configuration for zstd compression.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

level: Option<NonZeroU8>

The compression level to use.

The current range is 1-22, where 1 is fastest and 22 is best compression. Values above 20 should be used with caution, as they require additional memory.

If None, zstd’s default level is used.

Implementations

impl ZstdConfig

pub fn new(level: u8) -> Self

Create a new zstd configuration with the specified compression level.

pub const fn default_level() -> Self

Create a new zstd configuration with default compression level.

pub fn level(&self) -> i32

Returns the zstd compression level to pass to the zstd library.

Uses [zstd::DEFAULT_COMPRESSION_LEVEL] if the level is not set.

Trait Implementations

impl Clone for ZstdConfig

fn clone(&self) -> ZstdConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ZstdConfig

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

Formats the value using the given formatter.

impl Default for ZstdConfig

fn default() -> ZstdConfig

Returns the “default value” for a type.

impl PartialEq for ZstdConfig

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