Enum whiteread::stream::Error

pub enum Error {
    TooShort(Progress),
    Leftovers,
    ParseError,
    IoError(Error),
}

Error which can occur while parsing FromStream object.

It's convertible into io::Error, so it composes well with other reading functions.

Examples

if let Err(TooShort(Nothing)) = parse_string::<(u8, u16)>("") {} else { panic!(); }
if let Err(TooShort(Partial)) = parse_string::<(u8, u16)>("1") {} else { panic!(); }
if let Err(Leftovers) = parse_string::<char>("x y z") {} else { panic!(); }
if let Err(ParseError) = parse_string::<i32>("seven") {} else { panic!(); }

Variants

TooShort(Progress)

There was not enough input to parse a value.

Leftovers

Excessive input was provided.

ParseError

Parse error occured (data was in invalid format).

IoError(Error)

IO Error occured.

Methods

Checks if error variant is Partial flavour of TooShort

pub fn is_leftovers(&self) -> bool

Checks if error variant is Leftovers

pub fn is_parse_error(&self) -> bool

Checks if error variant is ParseError

pub fn is_io_error(&self) -> bool

Checks if error variant is IoError

Trait Implementations

impl Error for Error

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.

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

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

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