Enum encode_unicode::error::InvalidUtf16Tuple

pub enum InvalidUtf16Tuple {
    FirstIsTrailingSurrogate,
    SuperfluousSecond,
    MissingSecond,
    InvalidSecond,
}

Reasons why one or two u16s are not valid UTF-16, in sinking precedence.

Variants

FirstIsTrailingSurrogate

The first unit is a trailing/low surrogate, which is never valid.

Note that the value of a low surrogate is actually higher than a high surrogate.

SuperfluousSecond

You provided a second unit, but the first one stands on its own.

MissingSecond

The first and only unit requires a second unit.

InvalidSecond

The first unit requires a second unit, but it’s not a trailing/low surrogate.

Note that the value of a low surrogate is actually higher than a high surrogate.
