Enum Os 

pub enum Os {
    Linux,
    Darwin,
    Windows,
    FreeBsd,
    NetBsd,
    OpenBsd,
    Wasi,
    None,
}

The operating-system family a triple names.

This is what the bundled headers branch on — errno, the standard streams, mbstate_t, struct tm, time_t, FILE — through the _WIN32 and __APPLE__ macros the model predefines. A family whose library layout differs therefore has to be a variant here rather than a guess.

Variants

Linux

Linux, whatever the C library: gnu, musl, uclibc, android.

Darwin

Apple’s platforms: macOS, iOS, tvOS, watchOS, visionOS.

Windows

Windows, msvc and gnu alike.

FreeBsd

FreeBSD.

NetBsd

NetBSD.

OpenBsd

OpenBSD.

Wasi

WASI.

None

No operating system at all: a -none triple, and wasm32-unknown-unknown.

Implementations

impl Os

pub fn as_str(self) -> &'static str

The name used in diagnostics and in the documentation table.

pub fn macros(self) -> &'static [(&'static str, &'static str)]

The __linux__-style macros this operating system predefines.

_WIN64 is not here: it follows the pointer width rather than the system, so TargetModel::macros adds it.

Trait Implementations

impl Clone for Os

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Os

impl Debug for Os

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

Formats the value using the given formatter.

impl Eq for Os

impl Hash for Os

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 Os

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.
