Struct internship::IStr

[+] Show declaration

pub struct IStr(_);

[−] Expand description

Interned string type

IStr is designed for drop-in-replacement of immutable String.

Conceptually, IStr is similar to Rc<str> as both are immutable and zero-copy shareable. But IStr is interned, and inlined if small enough.
