[−][src]Crate null_terminated
Library of null-terminated slices and UTF-8-encoded strings, references to which are thin pointers for efficiency and ease of use with FFI
The likely primary use cases are C FFI and OS ABI (for example: on Unix, many system calls take, and the initial environment involves, null-terminated arguments).
As the representation is a bare pointer to the element type, one can declare foreign
functions which merely take arguments or return values of type Nul<_>
, for example:
extern "C" { fn strlen(_: &Nul<u8>) -> usize; fn strchr(_: &Nul<u8>, _: c_int) -> &Nul<u8>; }
For further examples, see the docs of Nul
.
