Struct arrow2::io::parquet::write::ZstdLevel

pub struct ZstdLevel(/* private fields */);

Represents a valid zstd compression level.

Implementations

impl ZstdLevel

pub fn try_new(level: i32) -> Result<ZstdLevel, Error>

Attempts to create a zstd compression level from a given compression level.

Compression levels must be valid (i.e. be acceptable for [zstd::compression_level_range]).

pub fn compression_level(&self) -> i32

Returns the compression level.

Trait Implementations

impl Clone for ZstdLevel

fn clone(&self) -> ZstdLevel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ZstdLevel

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

Formats the value using the given formatter.

impl Hash for ZstdLevel

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 PartialEq for ZstdLevel

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

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

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

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