Struct regex_syntax::error::Formatter

pub struct Formatter<'e, E> {

    span: &'e Span,
    aux_span: Option<&'e Span>,
}
Expand description

A helper type for formatting nice error messages.

This type is responsible for reporting regex parse errors in a nice human readable format. Most of its complexity is from interspersing notational markers pointing out the position where an error occurred.

Fields§

§pattern: &'e str

The original regex pattern in which the error occurred.

§err: &'e E

The error kind. It must impl fmt::Display.

§span: &'e Span

The primary span of the error.

§aux_span: Option<&'e Span>

An auxiliary and optional span, in case the error needs to point to two locations (e.g., when reporting a duplicate capture group name).
