Enum FromStrError

pub enum FromStrError {
    MultipleCodepoints,
    Empty,
}

Reasons why Utf8Char::from_str() or Utf16Char::from_str() failed.

Variants

MultipleCodepoints

Utf8Char or Utf16Char cannot store more than a single codepoint.

Empty

Utf8Char or Utf16Char cannot be empty.

Trait Implementations

impl Clone for FromStrError

fn clone(&self) -> FromStrError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FromStrError

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

Formats the value using the given formatter.

impl Display for FromStrError

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

Formats the value using the given formatter.

impl Error for FromStrError

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

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

Returns 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>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for FromStrError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
