Struct rustc_target::spec::Target[][src]

pub struct Target {
    pub llvm_target: String,
    pub pointer_width: u32,
    pub arch: String,
    pub data_layout: String,
    pub options: TargetOptions,

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

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


llvm_target: String

Target triple to pass to LLVM.

pointer_width: u32

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

arch: String

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

data_layout: String

Data layout to pass to LLVM.

options: TargetOptions

Optional settings with defaults.


impl Target[src]

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

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

pub fn min_atomic_width(&self) -> u64[src]

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

pub fn max_atomic_width(&self) -> u64[src]

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

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

pub fn from_json(obj: Json) -> Result<Target, String>[src]

Loads a target descriptor from a JSON object.

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

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 Clone for Target[src]

impl Debug for Target[src]

impl Deref for Target[src]

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.
