Enum TargetSpecVersion

pub enum TargetSpecVersion {
    Rustc_1_85_0,
    Rustc_1_76_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

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).

Implementations

impl TargetSpecVersion

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