Expand description

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

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


§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.


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

Returns a None if the UNSUPPORTED_CALLING_CONVENTIONS lint should be emitted

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

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

Loads a target descriptor from a JSON object.

Load a built-in target

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>§


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

Trait Implementations§

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more

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.

The resulting type after dereferencing.
Dereferences the value.
Mutably dereferences the value.
This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Gets the TypeId of self. Read more
Immutably borrows from an owned value. Read more
Mutably borrows from an owned value. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

The resulting type after obtaining ownership.
Creates owned data from borrowed data, usually by cloning. Read more
Uses borrowed data to replace owned data, usually by cloning. Read more
The type returned in the event of a conversion error.
Performs the conversion.
The type returned in the event of a conversion error.
Performs the conversion.


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.
