Variants

AddrOf

Takes the value off the top of the stack and writes it into linear memory. Pushes the address in linear memory as an i32.

I32FromPointer

Converts a language-specific pointer value to a wasm i32.

I32FromConstPointer

Converts a language-specific pointer value to a wasm i32.

PointerFromI32

Converts a core wasm i32 to a language-specific pointer.

Fields of PointerFromI32

ty: &'a TypeRef

ConstPointerFromI32

Converts a core wasm i32 to a language-specific pointer.

Fields of ConstPointerFromI32

ty: &'a TypeRef

ReuseReturn

This is a special instruction specifically for the original ABI of WASI. The raw return i32 of a function is re-pushed onto the stack for reuse.

Implementations

impl WitxInstruction<'_>

pub fn operands_len(&self) -> usize
