Enum witnext::WitxInstruction[−][src]

pub enum WitxInstruction<'a> {
    AddrOf,
    I32FromPointer,
    I32FromConstPointer,
    PointerFromI32 {
        ty: &'a TypeRef,

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 native wasm i32 to a language-specific pointer.

Fields of PointerFromI32

ty: &'a TypeRef
ConstPointerFromI32

Converts a native 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.
