Struct target_spec::Triple

pub struct Triple { /* private fields */ }

A single, specific target, uniquely identified by a triple.

A Triple may be constructed through new or the FromStr implementation.

Every Platform has one of these, and an evaluation TargetSpec may be backed by one of these as well.

Examples

use target_spec::Triple;

// Parse a simple target.
let target = Triple::new("x86_64-unknown-linux-gnu").unwrap();
// This is not a valid triple.
let err = Triple::new("cannot-be-known").unwrap_err();

Implementations

impl Triple

pub fn new(
    triple_str: impl Into<Cow<'static, str>>
) -> Result<Self, TripleParseError>

Creates a new Triple from a triple string.

pub fn as_str(&self) -> &str

Returns the string corresponding to this triple.

pub fn eval(&self, platform: &Platform) -> bool

Evaluates this triple against the given platform.

This simply compares self against the Triple the platform is based on, ignoring target features and flags.

Trait Implementations

impl Clone for Triple

fn clone(&self) -> Triple

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Triple

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

Formats the value using the given formatter.

impl FromStr for Triple

type Err = TripleParseError

The associated error which can be returned from parsing.

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

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

impl Hash for Triple

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,

Feeds a slice of this type into the given Hasher.

impl Ord for Triple

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Triple> for Triple

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<Triple> for Triple

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
