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.
Number of bits in a pointer. Influences the
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.
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>§
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
Deref implementation is no longer necessary.
Auto Trait Implementations§
Returns the argument unchanged.
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.
