Implementations

impl Version

pub fn supported(self) -> bool

Check if this version is supported at runtime.

impl Version

pub fn get_override() -> Option<Version>

Get the global version override, if any.

This function will return Some containing the version provided to Version::set_override if it was previously called, or None otherwise.

All dynamic dispatch implementations should respect this value.

pub fn set_override(version: Version)

Set the global version override.

Panics

This function will panic if any of the following conditions are met:

• The provided version is not supported.

• This function is called more than once.

• This function is called after calling Version::get_override (or any multiversioned dynamic dispatch function that respects the global override).

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl Default for Version

fn default() -> Version

Returns the “default value” for a type.

impl FromStr for Version

fn from_str(x: &str) -> Result<Self, Self::Err>

Implementation is case-insensitive.

type Err = UnknownVersion

The associated error which can be returned from parsing.

impl Hash for Version

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

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 PartialEq for Version

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