Constant(Handle<ConstantId>)

Only for decoration SpecId.

String(CompilerStr<'a>)

Only for decoration HlslSemanticGOOGLE and UserTypeGOOGLE.

Present

All other decorations to indicate the presence of a decoration.

Implementations

impl DecorationValue<'_>

pub const fn unset() -> Option<Self>

Helper function to unset a decoration value, to be passed to Compiler::set_decoration.

pub fn as_literal(&self) -> Option<u32>

Get the value if it is a literal u32.

impl DecorationValue<'_>

pub fn type_is_valid_for_decoration(&self, decoration: Decoration) -> bool

Check that the value is valid for the decoration type.

Trait Implementations

impl<'a> Clone for DecorationValue<'a>

fn clone(&self) -> DecorationValue<'static>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for DecorationValue<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a str> for DecorationValue<'a>

fn from(value: &'a str) -> Self

Converts to this type from the input type.

impl From<()> for DecorationValue<'_>

fn from(_value: ()) -> Self

Converts to this type from the input type.

impl<'a> From<CompilerStr<'a>> for DecorationValue<'a>

fn from(value: CompilerStr<'a>) -> Self

Converts to this type from the input type.

impl From<Handle<ConstantId>> for DecorationValue<'_>

fn from(value: Handle<ConstantId>) -> Self

Converts to this type from the input type.

impl From<String> for DecorationValue<'_>

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<u32> for DecorationValue<'_>

fn from(value: u32) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for DecorationValue<'a>

fn eq(&self, other: &DecorationValue<'a>) -> 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 ToStatic for DecorationValue<'_>

type Static<'a> = DecorationValue<'static> where 'a: 'static

The static type to return.

fn to_static(&self) -> Self::Static<'static>

Clone the object into an instance with 'static lifetime.
