as

The as keyword renames an imported symbol (to avoid clashes) and is also used for explicit type conversions/casts.

Syntax & Example​

import { HashMap as Map } from "adesh_alloc";

let big: i64 = 256;
let small = big as u8;

Use Cases​

  • Aliasing imports to resolve name conflicts.
  • Performing explicit, checked type conversions.
  • Renaming exports for a cleaner public API.
