Certain target environments impose additional restrictions on SPIR-V, so it’s often necessary to specify which one applies. Universal_* implies an environment-agnostic SPIR-V.

This enum MUST be kept in sync with the typedef enum spv_target_env in spirv-tools-sys/spirv-tools/include/spirv-tools/libspirv.h, it is being sent across the ffi boundary.

Implementations

impl TargetEnv

pub fn spirv_version(&self) -> (u8, u8)

Returns the (mayor, minor) version of spv this enum variant must at least support

The spirv versions for vulkan targets have been pulled from the source of the vulkan spec: https://github.com/KhronosGroup/Vulkan-Docs/blob/main/appendices/spirvenv.adoc?plain=1#L21

Trait Implementations

impl Clone for TargetEnv

fn clone(&self) -> TargetEnv

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TargetEnv

impl Debug for TargetEnv

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

Formats the value using the given formatter.

impl Default for TargetEnv

fn default() -> TargetEnv

Returns the “default value” for a type.

impl Display for TargetEnv

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

Formats the value using the given formatter.

impl FromStr for TargetEnv

type Err = SpirvResult

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for TargetEnv

fn eq(&self, other: &TargetEnv) -> 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.
