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.

type Iterator = CompressionIter

fn iter() -> CompressionIter

impl<'py> IntoPyObject<'py> for Compression

type Target = Compression

The Python output type

type Output = Bound<'py, <Compression as IntoPyObject<'py>>::Target>

The smart pointer type to use.

type Error = PyErr

The type returned in the event of a conversion error.

fn into_pyobject( self, py: Python<'py>, ) -> Result<<Self as IntoPyObject<'_>>::Output, <Self as IntoPyObject<'_>>::Error>

Performs the conversion.

impl Ord for Compression

fn cmp(&self, other: &Compression) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

impl PartialEq for Compression

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

Tests for self and other values to be equal, and is used by ==.

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

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<Compression>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
