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: String

Target triple to pass to LLVM.

target_endian: String

String to use as the target_endian cfg variable.

target_pointer_width: String

String to use as the target_pointer_width cfg variable.

target_c_int_width: String

Width of c_int type

target_os: String

OS name to use for conditional compilation.

target_env: String

Environment name to use for conditional compilation.

target_vendor: String

Vendor name to use for conditional compilation.

arch: String

Architecture to use for ABI considerations. Valid options: "x86", "x86_64", "arm", "aarch64", "mips", "powerpc", and "powerpc64".

data_layout: String

Data layout to pass to LLVM.

linker_flavor: LinkerFlavor

Linker flavor

options: TargetOptions

Optional settings with defaults.

Methods

impl Target

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

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

pub fn min_atomic_width(&self) -> u64

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

pub fn max_atomic_width(&self) -> u64

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

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

pub fn from_json(obj: Json) -> TargetResult

Load a target descriptor from a JSON object.

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

Search RUST_TARGET_PATH for a JSON file specifying the given target triple. 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.

Trait Implementations

impl PartialEq for Target

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

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

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

This method tests for !=.

impl Clone for Target

fn clone(&self) -> Target

Returns a copy 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

Formats the value using the given formatter.

impl<'a> HasTargetSpec for &'a Target

fn target_spec(&self) -> &Target

impl ToJson for Target

fn to_json(&self) -> Json

Converts the value of self to an instance of JSON
