Type Definition widestring::U16CString

type U16CString = UCString<u16>;

An owned, mutable C-style “wide” string for FFI that is nul-aware and nul-terminated.

U16CString is aware of nul values. Unless unchecked conversions are used, all U16CString strings end with a nul-terminator in the underlying buffer and contain no internal nul values. The strings may still contain invalid or ill-formed UTF-16 data. These strings are intended to be used with FFI functions such as Windows API that may require nul-terminated strings.

U16CString can be converted to and from many other string types, including U16String, OsString, and String, making proper Unicode FFI safe and easy.

Examples

The following example constructs a U16CString and shows how to convert a U16CString to a regular Rust String.

use widestring::U16CString;
let s = "Test";
// Create a wide string from the rust string
let wstr = U16CString::from_str(s).unwrap();
// Convert back to a rust string
let rust_str = wstr.to_string_lossy();
assert_eq!(rust_str, "Test");
