pub struct CStr { /* private fields */ }Expand description
A borrowed BSON-spec cstring: Zero or more UTF-8 encoded characters, excluding the nul byte.
Can be constructed at compile-time via the cstr! macro or at run-time from
a str via TryFrom.
Unlike std::ffi::CStr, this is required to be valid UTF-8, and does not include the nul
terminator in the buffer:
// std::ffi::CStr accepts invalid UTF-8:
let invalid: &std::ffi::CStr = c"\xc3\x28";ⓘ
// bson::raw::CStr does not:
let invalid: &bson::raw::CStr = cstr!("\xc3\x28"); // will not compile// &str accepts embedded nil characters:
let invalid: &str = "foo\0bar";ⓘ
// bson::raw::CStr does not:
let invalid: &bson::raw::CStr = cstr!("foo\0bar"); // will not compileImplementations§
