Struct Target 

pub struct Target { /* private fields */ }

A compilation target, identified by an LLVM-style triple.

Target wraps [target_lexicon::Triple] so the parser, validator, and host-detection logic come “for free” from the upstream crate. Anything LLVM understands is accepted; only the targets in Target::all() are “blessed” (i.e. tested and supported).

Implementations

impl Target

pub fn host() -> Target

The host machine’s target, evaluated at compile time.

pub fn from_triple(triple: Triple) -> Target

Construct a target from a [target_lexicon::Triple].

pub fn triple(&self) -> &Triple

The underlying [target_lexicon::Triple].

pub fn triple_string(&self) -> String

The triple as a string suitable for passing to LLVM (e.g. "x86_64-unknown-linux-gnu").

pub fn arch(&self) -> Arch

The CPU architecture component of this target.

pub fn os(&self) -> Os

The operating system component of this target.

pub fn is_elf(&self) -> bool

Whether this target uses ELF object format.

pub fn is_macho(&self) -> bool

Whether this target uses Mach-O object format.

pub fn all() -> Vec<Target>

The curated list of “blessed” targets — those Gruel explicitly tests and supports. Other LLVM-known triples are accepted (from_str succeeds) but unblessed.

pub fn is_blessed(&self) -> bool

Whether the triple is in the blessed list.

pub fn all_names() -> String

Comma-separated string of all blessed target names for help text.

Trait Implementations

impl Clone for Target

fn clone(&self) -> Target

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Target

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

Formats the value using the given formatter.

impl Default for Target

fn default() -> Target

Returns the “default value” for a type.

impl Display for Target

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

Formats the value using the given formatter.

impl FromStr for Target

fn from_str(s: &str) -> Result<Target, <Target as FromStr>::Err>

Parse a target from any LLVM-understood triple. Accepts a few short-form aliases (x86_64-linux, aarch64-linux, aarch64-macos, arm64-linux, arm64-macos) used historically by the CLI.

type Err = TargetParseError

The associated error which can be returned from parsing.

impl Hash for Target

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 Target

fn eq(&self, other: &Target) -> 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.
