Fields of LabelNotFound

label: Stringline: Option<usize>

InvalidOrigin(TryFromIntError)

An invalid warrior origin (not a positive integer) was specified.

InvalidSyntax(Error<Rule>)

The input string was ill-formed Redcode syntax.

InvalidArguments

The given opcode was not given enough arguments.

Fields of InvalidArguments

opcode: Opcode

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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 occurred.

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

impl From<Error<Rule>> for Error

fn from(source: Error<Rule>) -> Self

Performs the conversion.

impl<T> From<Error> for Result<T>

fn from(err: Error) -> Self

Performs the conversion.

impl From<TryFromIntError> for Error

fn from(source: TryFromIntError) -> Self

Performs the conversion.

impl PartialEq<Error> for Error

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

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

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

This method tests for !=.
