Macro for_each_visit_simd_operator

macro_rules! for_each_visit_simd_operator {
    ($m:ident) => { ... };
}

Available on crate feature simd only.

Used to implement the VisitSimdOperator trait.

The list of specializable Wasm proposals is as follows:

• @simd: Wasm simd proposal
• @relaxed_simd: Wasm relaxed-simd proposal

For more information about the structure and use of this macro please refer to the documentation of the for_each_operator macro.

pub struct VisitAndDoNothing;

impl<'a> wasmparser::VisitOperator<'a> for VisitAndDoNothing {
    type Output = ();

    // implement all the visit methods ..
}

macro_rules! define_visit_simd_operator {
    // The outer layer of repetition represents how all operators are
    // provided to the macro at the same time.
    //
    // The `$proposal` identifier is either `@simd` or `@relaxed_simd`.
    //
    // The shape of this macro is identical to [`for_each_visit_operator`].
    // Please refer to its documentation if you want to learn more.
