Error enum for brainfuck runtime errors

Variants

MismatchedBrackets

returned when the amount of [ in the code does not equal the amount of ]

Fields

opening: usize

the amount of [ in the code

closing: usize

the amount of ] in the code

FileReadError(Error)

propogated from opening or reading files for the brainfuck source code to be interpreted, in crate::Brainfuck::from_file

Tuple Fields

0: Error

the propogated error

IoError(Error)

propogated from . and , I/O operations

Tuple Fields

0: Error

the propogated error

MaxInstructionsExceeded(usize)

returned when the amount of instructions executed reaches the limit of instructions to be executed that is set

Tuple Fields

0: usize

the instructions limit that was set

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

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

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 From<Error> for Error

fn from(err: IoError) -> Self

Converts to this type from the input type.
