[−][src]Crate js_intern
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, strings 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)
