Struct `Error`

pub struct Error { /* private fields */ }

An error that occurred while parsing a regular expression into an abstract syntax tree.

Note that not all ASTs represents a valid regular expression. For example, an AST is constructed without error for \p{Quux}, but Quux is not a valid Unicode property name. That particular error is reported when translating an AST to the high-level intermediate representation (HIR).

Implementations

`impl Error`

fn kind(&self) -> &ErrorKind

Return the type of this error.

fn pattern(&self) -> &str

The original pattern string in which this error occurred.

Every span reported by this error is reported in terms of this string.

fn span(&self) -> &Span

Return the span at which this error occurred.

fn auxiliary_span(&self) -> Option<&Span>

Return an auxiliary span. This span exists only for some errors that benefit from being able to point to two locations in the original regular expression. For example, "duplicate" errors will have the main error position set to the duplicate occurrence while its auxiliary span will be set to the initial occurrence.
