Trait NativeWasmType

pub trait NativeWasmType: Sized {
    type Abi: Copy + Debug;

    const WASM_TYPE: Type;
}

NativeWasmType represents a Wasm type that has a direct representation on the host (hence the “native” term).

It uses the Rust Type system to automatically detect the Wasm type associated with a native Rust type.

use wasmer_types::{NativeWasmType, Type};

let wasm_type = i32::WASM_TYPE;
assert_eq!(wasm_type, Type::I32);

Note: This strategy will be needed later to automatically detect the signature of a Rust function.

Required Associated Constants

const WASM_TYPE: Type

Type for this NativeWasmType.

Required Associated Types

type Abi: Copy + Debug

The ABI for this type (i32, i64, f32, f64)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
