Implementations

impl CompressionFormat

pub fn from_str(s: &str) -> Self

Parse a CompressionFormat from a string, falling back to defaults if the string is not valid.

Trait Implementations

impl Arbitrary for CompressionFormat

type Parameters = (<CompressionLevel<1, 11, 1> as Arbitrary>::Parameters, <CompressionLevel<1, 22, 1> as Arbitrary>::Parameters, <CompressionLevel<1, 9, 6> as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Union<BoxedStrategy<CompressionFormat>>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for CompressionFormat

fn clone(&self) -> CompressionFormat

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionFormat

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

Formats the value using the given formatter.

impl Default for CompressionFormat

fn default() -> CompressionFormat

Returns the “default value” for a type.

impl From<CompressionFormat> for Compression

fn from(value: CompressionFormat) -> Self

Converts to this type from the input type.

impl PartialEq for CompressionFormat

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