Struct Error

pub struct Error<'code> {
    pub buffer: Buffer<'code>,
    pub matched: usize,
    pub kind: Kind,
}

Information about the error which occured when the Lexer::lex failed.

Fields

buffer: Buffer<'code>

matched: usize

This is included not just for debug information, but also to allow lexerus_derive::Lexer to obtain some basic information about how many tokens were matched before the program failed. This is useful when debugging enum because it would not be immediately obvious which match pattern failed.

kind: Kind
