Struct ResolverMarkerEnvironment 

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

A wrapper type around MarkerEnvironment that ensures the Python version markers are release-only, to match the resolver’s semantics.

Implementations

impl ResolverMarkerEnvironment

pub fn markers(&self) -> &MarkerEnvironment

Returns the underlying MarkerEnvironment.

Methods from Deref<Target = MarkerEnvironment>

pub fn get_version(&self, key: CanonicalMarkerValueVersion) -> &Version

Returns of the PEP 440 version typed value of the key in the current environment

pub fn get_string(&self, key: CanonicalMarkerValueString) -> &str

Returns of the stringly typed value of the key in the current environment

pub fn implementation_name(&self) -> &str

Returns the name of the Python implementation for this environment.

This is equivalent to sys.implementation.name.

Some example values are: cpython.

pub fn implementation_version(&self) -> &StringVersion

Returns the Python implementation version for this environment.

This value is derived from sys.implementation.version. See PEP 508 environment markers for full details.

This is equivalent to sys.implementation.name.

Some example values are: 3.4.0, 3.5.0b1.

pub fn os_name(&self) -> &str

Returns the name of the operating system for this environment.

This is equivalent to os.name.

Some example values are: posix, java.

pub fn platform_machine(&self) -> &str

Returns the name of the machine for this environment’s platform.

This is equivalent to platform.machine().

Some example values are: x86_64.

pub fn platform_python_implementation(&self) -> &str

Returns the name of the Python implementation for this environment’s platform.

This is equivalent to platform.python_implementation().

Some example values are: CPython, Jython.

pub fn platform_release(&self) -> &str

Returns the release for this environment’s platform.

This is equivalent to platform.release().

Some example values are: 3.14.1-x86_64-linode39, 14.5.0, 1.8.0_51.

pub fn platform_system(&self) -> &str

Returns the system for this environment’s platform.

This is equivalent to platform.system().

Some example values are: Linux, Windows, Java.

pub fn platform_version(&self) -> &str

Returns the version for this environment’s platform.

This is equivalent to platform.version().

Some example values are: #1 SMP Fri Apr 25 13:07:35 EDT 2014, Java HotSpot(TM) 64-Bit Server VM, 25.51-b03, Oracle Corporation, Darwin Kernel Version 14.5.0: Wed Jul 29 02:18:53 PDT 2015; root:xnu-2782.40.9~2/RELEASE_X86_64.

pub fn python_full_version(&self) -> &StringVersion

Returns the full version of Python for this environment.

This is equivalent to platform.python_version().

Some example values are: 3.4.0, 3.5.0b1.

pub fn python_version(&self) -> &StringVersion

Returns the version of Python for this environment.

This is equivalent to '.'.join(platform.python_version_tuple()[:2]).

Some example values are: 3.4, 2.7.

pub fn sys_platform(&self) -> &str

Returns the name of the system platform for this environment.

This is equivalent to sys.platform.

Some example values are: linux, linux2, darwin, java1.8.0_51 (note that linux is from Python3 and linux2 from Python2).

Trait Implementations

impl Clone for ResolverMarkerEnvironment

fn clone(&self) -> ResolverMarkerEnvironment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolverMarkerEnvironment

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

Formats the value using the given formatter.

impl Deref for ResolverMarkerEnvironment

type Target = MarkerEnvironment

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<MarkerEnvironment> for ResolverMarkerEnvironment

fn from(value: MarkerEnvironment) -> Self

Converts to this type from the input type.

impl PartialEq for ResolverMarkerEnvironment

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