Enum ParseWithGrammarError 

pub enum ParseWithGrammarError {
    Runtime(GrammarRuntimeError),
    Parse(GrammarParseError),
}

Why parse_with_grammar produced no tree: the grammar did not compile, or the source did not parse.

Variants

Runtime(GrammarRuntimeError)

The grammar did not load for the native executor.

Parse(GrammarParseError)

The source was rejected.
