Struct winnow::error::InputError

source ·
pub struct InputError<I: Clone> {
    pub input: I,
    pub kind: ErrorKind,
}
Expand description

Capture input on error

This is useful for testing of generic parsers to ensure the error happens at the right location.

Note: context and inner errors (like from Parser::try_map) will be dropped.

Fields§

§input: I

The input stream, pointing to the location where the error occurred

§kind: ErrorKind

A rudimentary error kind
