pub struct FromUtf16Error(_);

A possible error value when converting a String from a UTF-16 byte slice.

This type is the error type for the from_utf16 method on String.

Examples

Basic usage:

// 𝄞mu<invalid>ic
let v = &[0xD834, 0xDD1E, 0x006d, 0x0075,
          0xD800, 0x0069, 0x0063];

assert!(String::from_utf16(v).is_err());
