A macro for interning JavaScript primitives.

Stores one copy of each distinct JavaScript primitive. For example, js_intern!("string") evaluates to a &JsValue but uses only one heap allocation and a one-time translation from the utf-8 Rust string to the utf-16 JavaScript string the first time the expression is evaluated. Furthermore, values are de-duplicated across the program. So, any time js_intern!(1.0) is used in the program, the same instance of the JavaScript number is used.

Supported types

  • &'static str Eg: js_intern!("str")
  • f64, f32 u8, u16, u32, i8, i16, i32 Eg: js_intern(1.0)
  • bool Eg: js_intern(true)
