Operating system of the target.

Note

This value is closely related to the second and third element of the platform target triple, though it is not identical.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl<'a> Os<'a>

pub fn as_str(&self) -> &str

String representing this target OS which matches #[cfg(target_os)]

pub fn from_str(os: impl Into<Cow<'a, str>>) -> Self

Tries to parse the given string as an Os falling back to Os::Other for unknown values.

pub fn target() -> Result<Self, VarError>

Gets the current target Os.

Trait Implementations

impl<'a> Clone for Os<'a>

fn clone(&self) -> Os<'a>

Returns a copy of the value.

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