Enum TargetSpecVersion 

pub enum TargetSpecVersion {
    Older,
    Rustc_1_85_0,
    Rustc_1_76_0,
    Rustc_1_93_0,
    Rustc_1_94_0,
}

Enum for different versions of target specs, to allow changing the target spec for different rust versions. The version listed in the enum is always the minimum version to require said target spec, with the newest version always at the top.

Variants

Older

Rustc_1_85_0

Introduced in 489c3ee6fd63da3ca7cf2b15e1ee709d8e078aab in the old v2 target spec way, later ported to here. remove os: unknown, add crt-static-respected: true

Rustc_1_76_0

rustc 1.76 has been tested to correctly parse modern target spec jsons. Some later version requires them. Some earlier version fails with them (notably our 0.9.0 release).

Rustc_1_93_0

rustc 1.93 requires that the value of “target-pointer-width” is no longer a string but u16

Rustc_1_94_0

rustc 1.94.0 destabilised json target specs, requiring -Ztarget-spec-json see https://github.com/Rust-GPU/rust-gpu/pull/545 see https://github.com/rust-lang/rust/pull/150151

Implementations

impl TargetSpecVersion

pub fn target_arg( rustc_version: Version, target: &SpirvTarget, target_spec_folder: &Path, ) -> Result<TargetSpec, Error>

Format the --target arg. On newer rustc versions, will create a compatible target spec json file and return the absolute path to it, on older rustc versions may return the target name.

pub fn from_rustc_version(rustc_version: Version) -> TargetSpecVersion

Returns the version of the target spec required for a certain rustc version. May return None if the version is old enough to not need target specs.

pub fn format_spec(&self, target: &SpirvTarget) -> String

format the target spec json

Trait Implementations

impl Clone for TargetSpecVersion

fn clone(&self) -> TargetSpecVersion

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TargetSpecVersion

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Ord for TargetSpecVersion

fn cmp(&self, other: &TargetSpecVersion) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TargetSpecVersion

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for TargetSpecVersion

fn partial_cmp(&self, other: &TargetSpecVersion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
