Struct wasmer::WasmCell

#[repr(transparent)]
pub struct WasmCell<'a, T: ?Sized> { /* fields omitted */ }

A mutable Wasm-memory location.

Implementations

impl<'a, T> WasmCell<'a, T>

pub const fn new(cell: &'a Cell<T>) -> WasmCell<'a, T>

Creates a new WasmCell containing the given value.

Examples

use std::cell::Cell;
use wasmer::WasmCell;

let cell = Cell::new(5);
let wasm_cell = WasmCell::new(&cell);

impl<'a, T: Copy> WasmCell<'a, T>

pub fn get(&self) -> T

Returns a copy of the contained value.

Examples

use std::cell::Cell;
use wasmer::WasmCell;

let cell = Cell::new(5);
let wasm_cell = WasmCell::new(&cell);
let five = wasm_cell.get();

impl<T: Sized> WasmCell<'_, T>

pub fn set(&self, val: T)

Sets the contained value.

Examples

use std::cell::Cell;
use wasmer::WasmCell;

let cell = Cell::new(5);
let wasm_cell = WasmCell::new(&cell);
wasm_cell.set(10);
assert_eq!(cell.get(), 10);
