Struct Error 

pub struct Error { /* private fields */ }

Parsing error, capturing the position in the input where the error was encountered.

Implementations

impl Error

pub fn new<E>(err: E, line: usize, col: usize) -> Error

where E: Into<ErrorKind>,

Construct an Error

pub fn kind(&self) -> &ErrorKind

Return the kind

pub fn position(&self) -> (usize, usize)

Return the position in the input.

NB: lines and columns are numbered from 0.

pub fn in_context(&self, context: &str) -> String

Display this error with context.

This method numbers line and column starting from 1 instead of 0, as expected by text editors.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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(source: Error) -> Error

Converts to this type from the input type.
