Struct PythonVersion 

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

Implementations

impl PythonVersion

pub fn markers(&self, base: &MarkerEnvironment) -> MarkerEnvironment

Return a MarkerEnvironment compatible with the given PythonVersion, based on a base MarkerEnvironment.

The returned MarkerEnvironment will preserve the base environment’s platform markers, but override its Python version markers.

pub fn python_version(&self) -> Version

Return the python_version marker corresponding to this Python version.

This should include exactly a major and minor version, but no patch version.

Ex) python_version == "3.12"

pub fn python_full_version(&self) -> Version

Return the python_full_version marker corresponding to this Python version.

This should include exactly a major, minor, and patch version (even if it’s zero), along with any pre-release or post-release information.

Ex) python_full_version == "3.12.0b1"

pub fn version(&self) -> &Version

Return the full parsed Python version.

pub fn into_version(self) -> Version

Return the full parsed Python version.

pub fn major(&self) -> u8

Return the major version of this Python version.

pub fn minor(&self) -> u8

Return the minor version of this Python version.

pub fn patch(&self) -> Option<u8>

Return the patch version of this Python version, if set.

pub fn without_patch(&self) -> Self

Returns a copy of the Python version without the patch version

Methods from Deref<Target = Version>

pub fn any_prerelease(&self) -> bool

Whether this is an alpha/beta/rc or dev version

pub fn is_stable(&self) -> bool

Whether this is a stable version (i.e., not an alpha/beta/rc or dev version)

pub fn is_pre(&self) -> bool

Whether this is an alpha/beta/rc version

pub fn is_dev(&self) -> bool

Whether this is a dev version

pub fn is_post(&self) -> bool

Whether this is a post version

pub fn is_local(&self) -> bool

Whether this is a local version (e.g. 1.2.3+localsuffixesareweird)

When true, it is guaranteed that the slice returned by Version::local is non-empty.

pub fn epoch(&self) -> u64

Returns the epoch of this version.

pub fn release(&self) -> Release<'_>

Returns the release number part of the version.

pub fn pre(&self) -> Option<Prerelease>

Returns the pre-release part of this version, if it exists.

pub fn post(&self) -> Option<u64>

Returns the post-release part of this version, if it exists.

pub fn dev(&self) -> Option<u64>

Returns the dev-release part of this version, if it exists.

pub fn local(&self) -> LocalVersionSlice<'_>

Returns the local segments in this version, if any exist.

pub fn min(&self) -> Option<u64>

Returns the min-release part of this version, if it exists.

The “min” component is internal-only, and does not exist in PEP 440. The version 1.0min0 is smaller than all other 1.0 versions, like 1.0a1, 1.0dev0, etc.

pub fn max(&self) -> Option<u64>

Returns the max-release part of this version, if it exists.

The “max” component is internal-only, and does not exist in PEP 440. The version 1.0max0 is larger than all other 1.0 versions, like 1.0.post1, 1.0+local, etc.

pub fn only_release(&self) -> Version

Return the version with any segments apart from the release removed.

pub fn only_minor_release(&self) -> Version

Return the version with any segments apart from the minor version of the release removed.

pub fn only_release_trimmed(&self) -> Version

Return the version with any segments apart from the release removed, with trailing zeroes trimmed.

Trait Implementations

fn clone(&self) -> PythonVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PythonVersion

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

Formats the value using the given formatter.

impl Deref for PythonVersion

type Target = StringVersion

The resulting type after dereferencing.

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

Dereferences the value.

impl<'de> Deserialize<'de> for PythonVersion

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for PythonVersion

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

impl From<&PythonVersion> for VersionRequest

fn from(version: &PythonVersion) -> Self

Converts to this type from the input type.

impl From<StringVersion> for PythonVersion

fn from(version: StringVersion) -> Self

Converts to this type from the input type.

impl FromStr for PythonVersion

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 Hash for PythonVersion

impl PartialEq for PythonVersion

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