Struct konst::parsing::ParseError

source ·
pub struct ParseError<'a> { /* private fields */ }
Expand description

Error returned by all parsing methods that return Result.

This error type knows where the error happened, in what direction the string was being parsed, and the kind of error that happened.

Implementations§

source§

impl<'a> ParseError<'a>

source

pub const fn new(parser: Parser<'a>, kind: ErrorKind) -> Self

Constructs a ParseError.

source

pub const fn other_error( parser: Parser<'a>, extra_message: &'static &'static str, ) -> Self

Constructs a ParseError for an ErrorKind::Other error with a customized error message.

source

pub const fn copy(&self) -> Self

A const fn equivalent of a clone method.

source

pub const fn offset(&self) -> usize

Gets the byte offset of this error in the parsed string that the Parser was constructed from.

source

pub const fn error_direction(&self) -> ParseDirection

The direction that this error happened from, either from the start or the end.

source

pub const fn kind(&self) -> ErrorKind

The kind of parsing error that this is.

source

pub const fn panic(&self) -> !

For panicking with an error message, this is called by the unwrap_ctx macro.
