}
Expand description

The type of a core WebAssembly value.

Variants§

§

I32

The i32 type.

§

I64

The i64 type.

§

F32

The f32 type.

§

F64

The f64 type.

§

V128

The v128 type.

Part of the SIMD proposal.

§

Ref(RefType)

A reference type.

The funcref and externref type fall into this category and the full generalization here is due to the implementation of the function-references proposal.
