Struct utf8_chars::ReadCharError

pub struct ReadCharError { /* fields omitted */ }

A structure, containing read bytes, and an io::Error. The io::Error is an actual I/O error if some occurred, or a synthetic error with either the UnexpectedEof kind if a multi-byte char was unexpectedly terminated, either the InvalidData kind if no actual I/O error occurred, but read byte sequence was not recognised as a valid UTF-8.

Implementations

impl ReadCharError

pub fn as_bytes(&self) -> &[u8]

A byte sequence, representing an invalid or incomplete UTF-8-encoded char.

pub fn as_io_error(&self) -> &Error

Returns a reference to the I/O error.

pub fn into_io_error(self) -> Error

Consumes the ReadCharError, returning the I/O error.

Trait Implementations

impl Debug for ReadCharError

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

Formats the value using the given formatter.

impl Display for ReadCharError

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

Formats the value using the given formatter.

impl Error for ReadCharError

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

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

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
