Struct ParserError

Source

pub struct ParserError {
    pub kind: ParserErrorKind,
    pub location: Fragment,
    pub help: Option<Cow<'static, str>>,
}

Available on crate feature parser only.

Expand description

An error that occurred while parsing. This error structure is pretty simple compared to what can be represented using a diagnostic. That’s fine, since most of the more complex errors arise when typechecking, rather than checking syntax.

Fields§

§kind: ParserErrorKind

What type/cause there is for this error.

§location: Fragment

Where this error occurred.

§help: Option<Cow<'static, str>>

Optionally, a help string that can be printed with this error.
