Implementations

impl ZstdCompressionLevel

pub const fn new() -> Self

Creates a new ZstdCompressionLevel with the default level.

pub const fn with_level(level: i8) -> Self

Creates a new ZstdCompressionLevel with the level.

pub const fn level(&self) -> i8

Returns the level of the zstd algorithm.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for ZstdCompressionLevel

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Arbitrary for ZstdCompressionLevel

Available on crate features quickcheck only.

fn arbitrary(g: &mut Gen) -> Self

Return an arbitrary value.

fn shrink(&self) -> Box<dyn Iterator<Item = Self>>

Return an iterator of values that are smaller than itself.

impl Clone for ZstdCompressionLevel

fn clone(&self) -> ZstdCompressionLevel

Returns a duplicate 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 value” for a type.

impl<'de> Deserialize<'de> for ZstdCompressionLevel

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ZstdCompressionLevel

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

Formats the value using the given formatter.

impl From<i8> for ZstdCompressionLevel

fn from(value: i8) -> Self

Converts to this type from the input type.

impl From<u8> for ZstdCompressionLevel

fn from(value: u8) -> Self

Converts to this type from the input type.

impl FromStr for ZstdCompressionLevel

type Err = ParseZstdCompressionLevelError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ZstdCompressionLevel

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.

impl Serialize for ZstdCompressionLevel

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
