Expand description
A structured reason for a ParseError. Note that parsing in nu is more like macro expansion in other languages, so the kinds of errors that can occur during parsing are more contextual than you might expect.
Variants
Eof
The parser encountered an EOF rather than what it was expecting
ExtraTokens
The parser expected to see the end of a token stream (possibly the token stream from inside a delimited token node), but found something else.
Mismatch
The parser encountered something other than what it was expecting
Unclosed
Unclosed delimiter
GeneralError
An unexpected internal error has occurred
ArgumentError
The parser tried to parse an argument for a command, but it failed for some reason
