Source 
pub unsafe fn optional_cstr_to_str(ptr: *const c_char) -> Option<&'static str>
Expand description

§Safety

  • Assumes ptr is a valid C string pointer or NULL.
  • The returned slice is only valid while the original C string remains allocated.
  • Caller must ensure the C string outlives any usage of the returned slice.
