Struct xswag_syntax_java::lex::Error

pub struct Error<P> {
    pub report: Report,
    pub poison: Option<P>,
}

Type returned by the Tokenizer in case of a lexing error. Contains a detailed report and may contain poisoned token that could be used to proceed normally.

Fields

report: Report

Detailed information about the error. Intended for user-friendly compiler messages.

poison: Option<P>

If an error occured but the lexer is able to recover, it emits a token. This token will probably contain some "wrong" information. For example: the java code '\j' contains a character literal with a wrong escape code. In this case the error contains a poisened token "Char(j)". So the backslash is ignored in order to get some semi usable token.

Methods

impl<P> Error<P>

fn map_poison<F, U>(self, op: F) -> Error<U> where F: FnOnce(P) -> U

Returns a new version with a changed poison

fn map_report<F>(self, op: F) -> Error<P> where F: FnOnce(Report) -> Report

Returns a new version with a changed report
