Struct safer_ffi::char_p::char_p_ref[−][src]

#[repr(transparent)]
pub struct char_p_ref<'lt>(_, _);
Expand description

A #[repr(c)] null-terminated UTF-8 encoded string, for compatibility with both the C char * API and Rust’s str.

This is a borrowed version, i.e., with the semantics of &'lt CStr / &'lt str, but for it being a slim pointer.
