Struct PythonVersion 

pub struct PythonVersion { /* private fields */ }

Lightweight Python version metadata.

Implementations

impl PythonVersion

pub fn new( major: u16, minor: Option<u16>, patch: Option<u16>, ) -> Result<PythonVersion, PythonVersionParseError>

Creates Python version metadata.

Errors

Returns PythonVersionParseError::InvalidVersion when the major version is zero or a patch component is present without a minor component.

pub const fn major(&self) -> u16

Returns the major version number.

pub const fn minor(&self) -> Option<u16>

Returns the optional minor version number.

pub const fn patch(&self) -> Option<u16>

Returns the optional patch version number.

pub const fn is_python3(&self) -> bool

Returns whether this version is in the Python 3 family.

pub fn is_prerelease_like(&self) -> bool

Returns whether the parsed suffix looks like a prerelease marker.

pub fn suffix(&self) -> Option<&str>

Returns the parsed non-numeric suffix when one was present.

Trait Implementations

impl Clone for PythonVersion

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<(), Error>

Formats the value using the given formatter.

impl Display for PythonVersion

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

Formats the value using the given formatter.

impl FromStr for PythonVersion

type Err = PythonVersionParseError

The associated error which can be returned from parsing.

fn from_str( input: &str, ) -> Result<PythonVersion, <PythonVersion as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for PythonVersion

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PythonVersion

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for PythonVersion

fn partial_cmp(&self, other: &PythonVersion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
