🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

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

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

Methods

impl Target

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

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

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

pub fn min_atomic_width(&self) -> u64

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

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

pub fn max_atomic_width(&self) -> u64

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

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

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

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

pub fn from_json(obj: Json) -> TargetResult

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

Load a target descriptor from a JSON object.

pub fn search(target: &str) -> Result<Target, String>

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

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, __arg_0: &Target) -> bool

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

fn ne(&self, __arg_0: &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, __arg_0: &mut Formatter) -> Result
