Struct ParseError

pub struct ParseError<'a> { /* private fields */ }

Error signaling a signature parse failure. The error references the originally parsed string providing convenience methods to inspect where the error occurred.

Implementations

impl<'a> ParseError<'a>

pub fn position(&self) -> usize

Retrieves the error position in the parsed signature string.

pub fn message(&self) -> &str

Retrieves the parser error messages revealing what went wrong.

The Display implementation of ParseError prints exactly this (and only this) string.

pub fn context(&self) -> &str

Retrieves the (parse) context in which the error occurred. Useful only for debugging the parser.

pub fn signature(&self) -> &'a str

Retrieves the original, full signature string which failed to parsed and led to this error.

pub fn unconsumed(&self) -> &'a str

Returns the unconsumed portion of the parsed signature string at which the error occurred.

pub fn consumed(&self) -> &'a str

Retrieves the successfully consumed portion of the parsed signature string.
