# Struct FromUtf16Error

1.36.0 · Source

    pub struct FromUtf16Error { /* private fields */ }

Expand description

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

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

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