Enum holochain_wasmer_host::prelude::Value

pub enum Value {
    I32(i32),
    I64(i64),

    V128(u128),
}

Represents a WebAssembly value.

As the number of types in WebAssembly expand, this structure will expand as well.

Variants

I32(i32)

I64(i64)

The i64 type.

F32(f32)

The f32 type.

F64(f64)

The f64 type.

V128(u128)

The v128 type.
