Expand description

Everything rustc knows about how to compile for a specific target.

Every field here must be specified, and has no default value.

Fields§

§llvm_target: Cow<'static, str>

Target triple to pass to LLVM.

§pointer_width: u32

Number of bits in a pointer. Influences the target_pointer_width cfg variable.

§arch: Cow<'static, str>

Architecture to use for ABI considerations. Valid options include: “x86”, “x86_64”, “arm”, “aarch64”, “mips”, “powerpc”, “powerpc64”, and others.

§data_layout: Cow<'static, str>

Data layout to pass to LLVM.

§options: TargetOptions

Optional settings with defaults.

Implementations§

source§

impl Target

source§

impl Target

source

pub fn adjust_abi(&self, abi: Abi) -> Abi

Given a function ABI, turn it into the correct ABI for this target.

source

pub fn is_abi_supported(&self, abi: Abi) -> Option<bool>

Returns a None if the UNSUPPORTED_CALLING_CONVENTIONS lint should be emitted

source

pub fn min_atomic_width(&self) -> u64

Minimum integer size in bits that this target can perform atomic operations on.

source

pub fn max_atomic_width(&self) -> u64

Maximum integer size in bits that this target can perform atomic operations on.

source

pub fn from_json(obj: Json) -> Result<(Target, TargetWarnings), String>

Loads a target descriptor from a JSON object.

source

pub fn expect_builtin(target_triple: &TargetTriple) -> Target

Load a built-in target

source

pub fn search( target_triple: &TargetTriple, sysroot: &Path ) -> Result<(Target, TargetWarnings), String>

Search for a JSON file specifying the given target triple.

If none is found in $RUST_TARGET_PATH, look for a file called target.json inside the sysroot under the target-triple’s rustlib directory. Note that it could also just be a bare filename already, so also check for that. If one of the hardcoded targets we know about, just return it directly.

The error string could come from any of the APIs called, including filesystem access and JSON decoding.

Methods from Deref<Target = TargetOptions>§

source

fn add_post_link_args(&mut self, flavor: LinkerFlavor, args: &[&'static str])

source

fn update_from_cli(&mut self)

source

fn update_to_cli(&mut self)

Trait Implementations§

impl Clone for Target

source§

fn clone(&self) -> Target

Returns a copy of the value. Read more
1.0.0 · source§

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

Performs copy-assignment from source. Read more
source§

impl Debug for Target

source§

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

Formats the value using the given formatter. Read more
source§

impl Deref for Target

TargetOptions being a separate type is basically an implementation detail of Target that is used for providing defaults. Perhaps there’s a way to merge TargetOptions into Target so this Deref implementation is no longer necessary.

§

type Target = TargetOptions

The resulting type after dereferencing.
source§

fn deref(&self) -> &Self::Target

Dereferences the value.
source§

impl DerefMut for Target

source§

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
source§

impl HasTargetSpec for Target

source§

impl PartialEq<Target> for Target

source§

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

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

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.
source§

impl ToJson for Target

source§

fn to_json(&self) -> Json

source§

impl StructuralPartialEq for Target

Performs the conversion.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
