Struct Platform

#[non_exhaustive]
pub struct Platform {
    pub target_triple: &'static str,
    pub target_arch: Arch,
    pub target_os: OS,
    pub target_env: Env,
    pub target_pointer_width: PointerWidth,
    pub target_endian: Endian,
    pub tier: Tier,
}

Rust platforms supported by mainline rustc

Sourced from https://doc.rust-lang.org/nightly/rustc/platform-support.html as well as the latest nightly version of rustc

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

target_triple: &'static str

“Target triple” string uniquely identifying the platform. See: https://github.com/rust-lang/rfcs/blob/master/text/0131-target-specification.md

These are defined in the rustc_target crate of the Rust compiler: https://github.com/rust-lang/rust/blob/master/src/librustc_target/spec/mod.rs

target_arch: Arch

Target architecture cfg attribute (i.e. cfg(target_arch))

target_os: OS

Target OS cfg attribute (i.e. cfg(target_os)).

target_env: Env

Target environment cfg attribute (i.e. cfg(target_env)). Only used when needed for disambiguation, e.g. on many GNU platforms this value will be None.

target_pointer_width: PointerWidth

Target pointer width cfg attribute, in bits (i.e. cfg(target_pointer_width)). Typically 64 on modern platforms, 32 on older platforms, 16 on some microcontrollers.

target_endian: Endian

Target endianness cfg attribute (i.e. cfg(target_endian)). Set to “little” on the vast majority of modern platforms.

tier: Tier

Tier of this platform:

• Tier::One: guaranteed to work
• Tier::Two: guaranteed to build
• Tier::Three: unofficially supported with no guarantees

Implementations

impl Platform

pub const ALL: &'static [Platform] = ALL

All valid Rust platforms usable from the mainline compiler.

Note that this list will evolve over time, and platforms will be both added and removed.

pub fn find(target_triple: &str) -> Option<&'static Platform>

Find a Rust platform by its “target triple”, e.g. i686-apple-darwin

Trait Implementations

impl Clone for Platform

fn clone(&self) -> Platform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Platform

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

Formats the value using the given formatter.

impl Display for Platform

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

Formats the value using the given formatter.

impl Hash for Platform

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 Ord for Platform

fn cmp(&self, other: &Platform) -> 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 Platform

fn eq(&self, other: &Platform) -> 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 Platform

fn partial_cmp(&self, other: &Platform) -> 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.

impl Eq for Platform

impl StructuralPartialEq for Platform
