Enums§
- Cached
Constant 🔒 - Capability
- SPIR-V operand kind: Capability
- Dimension 🔒
- Error
- Local
Type 🔒 - A SPIR-V type constructed during code generation.
- Lookup
Type 🔒 - A type encountered during SPIR-V generation.
- Numeric
Type 🔒 - A numeric type, for use in
LocalType. - Source
Language - SPIR-V operand kind: SourceLanguage
- Wrapped
Function 🔒 - Key used to look up an operation which we have wrapped in a helper
function, which should be called instead of directly emitting code
for the expression. See
Writer::wrapped_functions. - Zero
