Enum encode_unicode::error::Utf16TupleError

pub enum Utf16TupleError {
    FirstIsTrailingSurrogate,
    SuperfluousSecond,
    MissingSecond,
    SecondIsNotTrailingSurrogate,
}

Error returned when one or two u16s are not valid UTF-16.

They are returned in sinking precedence; The condition that causes the first variant to be returned is checked for before the condition the next variant is returned for.

Variants

FirstIsTrailingSurrogate

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

SuperfluousSecond

The provided second unit is not necessary.

MissingSecond

The first and only unit requires a second unit.

SecondIsNotTrailingSurrogate

The second unit is needed and was provided, but is not a trailing surrogate.

Trait Implementations

impl Clone for Utf16TupleError

fn clone(&self) -> Utf16TupleError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Utf16TupleError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Utf16TupleError

fn description(&self) -> &'static str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide(&'a self, req: &mut Demand<'a>)

🔬 This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl PartialEq<Utf16TupleError> for Utf16TupleError

fn eq(&self, other: &Utf16TupleError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
