The “operating system” field, which sometimes implies an environment, and sometimes isn’t an actual operating system.

LLVM’s Apple triples may optionally include the deployment target.

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.

Unknown

Aix

AmdHsa

Bitrig

Cloudabi

Cuda

Cygwin

Darwin(Option<DeploymentTarget>)

The general Darwin core OS.

Generally, -mmacosx-version-min=... or similar flags are required by Clang to determine the actual OS (either macOS, iOS, tvOS, watchOS or visionOS).

WARNING: When parsing rustc target triples, this matches the macOS target triples as well.

Dragonfly

Emscripten

Espidf

Freebsd

Fuchsia

Haiku

Hermit

Horizon

Hurd

Illumos

IOS(Option<DeploymentTarget>)

L4re

Linux

MacOSX(Option<DeploymentTarget>)

macOS.

WARNING: This does not match the macOS triples when parsing rustc target triples, for that see the darwin OS name.

XROS(Option<DeploymentTarget>)

An alternate name for visionOS.

Implementations

impl OperatingSystem

pub const fn host() -> OperatingSystem

Return the operating system for the current host.

impl OperatingSystem

pub fn into_str(self) -> Cow<'static, str>

Convert into a string

pub fn is_like_darwin(&self) -> bool

Whether the OS is similar to Darwin.

This matches on any of:

• Darwin
• iOS
• macOS
• tvOS
• visionOS
• watchOS
• xrOS

Trait Implementations

impl Clone for OperatingSystem

fn clone(&self) -> OperatingSystem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OperatingSystem

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

Formats the value using the given formatter.

impl Display for OperatingSystem

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

Formats the value using the given formatter.

impl FromStr for OperatingSystem

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<OperatingSystem, ()>

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

impl Hash for OperatingSystem

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 PartialEq for OperatingSystem

fn eq(&self, other: &OperatingSystem) -> 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 Copy for OperatingSystem

impl Eq for OperatingSystem

impl StructuralPartialEq for OperatingSystem
