Struct InputError 

pub struct InputError { /* private fields */ }

Error type that shows the error’s location in the input, returned by puzzle new functions.

Examples

let input = "12 34\n56 78\n90 abc";
let error = InputError::new(input, 15, "expected number");
assert_eq!(error.to_string(), "
invalid input: expected number
  --> line 3 column 4
  |
3 | 90 abc
  |    ^
".trim_start());

Implementations

impl InputError

pub fn new( input: &str, index: impl ToIndex, source: impl Into<Box<dyn Error>>, ) -> Self

Create a new InputError.

See ToIndex implementations for details on supported indexes.

pub fn into_source(self) -> Box<dyn Error>

Returns the source error.

Trait Implementations

impl Debug for InputError

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

Formats the value using the given formatter.

impl Display for InputError

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

Formats the value using the given formatter.

impl Error for InputError

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.
