Enum alloc::string::ParseError

pub enum ParseError {}

An error when parsing a String.

This enum is slightly awkward: it will never actually exist. This error is part of the type signature of the implementation of FromStr on String. The return type of from_str, requires that an error be defined, but, given that a String can always be made into a new String without error, this type will never actually be returned. As such, it is only here to satisfy said signature, and is useless otherwise.

Trait Implementations

impl Error for ParseError

fn description(&self) -> &str

This method is soft-deprecated.

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

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

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

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

impl Eq for ParseError

impl PartialEq<ParseError> for ParseError

fn eq(&self, &ParseError) -> bool

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

#[must_use]

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

This method tests for !=.

impl Copy for ParseError

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

fn fmt(&self, &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for ParseError

fn fmt(&self, &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.
