Struct ParserError 

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

Available on crate feature parser only.

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: Vec<Cow<'static, str>>

Optional help strings that can be printed with this error.
