Enum python_packaging::interpreter::MultiprocessingStartMethod

pub enum MultiprocessingStartMethod {
    None,
    Fork,
    ForkServer,
    Spawn,
    Auto,
}

Defines how to call multiprocessing.set_start_method() when multiprocessing is imported.

When set to a value that is not none, when oxidized_importer.OxidizedFinder services an import of the multiprocessing module, it will automatically call multiprocessing.set_start_method() to configure how worker processes are created.

If the multiprocessing module is not imported by oxidized_importer.OxidizedFinder, this setting has no effect.

Serialization type: string

Variants

None

Do not call multiprocessing.set_start_method().

This mode is what Python programs do by default.

Serialized value: none

Fork

Call with value fork.

Serialized value: fork

ForkServer

Call with value forkserver

Serialized value: forkserver

Spawn

Call with value spawn

Serialized value: spawn

Auto

Call with a valid appropriate for the given environment.

This likely maps to spawn on Windows and fork on non-Windows.

Serialized value: auto

Trait Implementations

impl Clone for MultiprocessingStartMethod

fn clone(&self) -> MultiprocessingStartMethod

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MultiprocessingStartMethod

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

Formats the value using the given formatter.

impl From<MultiprocessingStartMethod> for String

fn from(v: MultiprocessingStartMethod) -> Self

Converts to this type from the input type.

impl FromStr for MultiprocessingStartMethod

type Err = String

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 PartialEq<MultiprocessingStartMethod> for MultiprocessingStartMethod

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

impl ToString for MultiprocessingStartMethod

fn to_string(&self) -> String

Converts the given value to a String.

impl TryFrom<&str> for MultiprocessingStartMethod

type Error = String

The type returned in the event of a conversion error.

fn try_from(v: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for MultiprocessingStartMethod

type Error = String

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.
