Implementations

impl StaticString

pub fn as_ptr(&self) -> *const c_char

pub fn register(str: &str) -> Self

Turns a given string into a *c_char which has static lifetime measured from the moment this function returns. Registering the same string multiple times behaves like interning (will not use additional resources).

WARNING: this function creates data with static lifetime. It should only be called on a finite set of unique strings. Using it on a non-finite set will appear to be a memory leak since the space used will grow without bound.
