## Description:
|
|
|
|
The `wasm` module is a pure V implementation of the WebAssembly bytecode module format,
|
|
available in the form of a builder.
|
|
|
|
It allows users to generate WebAssembly modules in memory.
|
|
|
|
With the V wasm module, users can create functions, opcodes, and utilize the entire wasm
|
|
specification without the need for a large dependency like binaryen. All of this
|
|
functionality is available within V itself, making the module a valuable resource for
|
|
V developers seeking to build high-performance web applications.
|
|
|
|
The module is designed to generate a `[]u8`, which can be written to a `.wasm` file
|
|
or executed in memory.
|
|
|
|
```v
|
|
import wasm
|
|
import os
|
|
|
|
fn main() {
|
|
mut m := wasm.Module{}
|
|
mut func := m.new_function('add', [.i32_t, .i32_t], [.i32_t])
|
|
{
|
|
func.local_get(0) // | local.get 0
|
|
func.local_get(1) // | local.get 1
|
|
func.add(.i32_t) // | i32.add
|
|
}
|
|
m.commit(func, true) // `export: true`
|
|
|
|
mod := m.compile() // []u8
|
|
|
|
os.write_file_array('add.wasm', mod)!
|
|
}
|
|
```
|
|
|
|
This module does not perform verification of the WebAssembly output.
|
|
Use a tool like `wasm-validate` to validate, and `wasm-dis` to show a decompiled form.
