Enum peg_runtime::RuleResult

source · [−]

pub enum RuleResult<T> {
    Matched(usize, T),
    Failed,
}

Expand description

The result type used internally in the parser.

You’ll only need this if implementing the Parse* traits for a custom input type. The public API of a parser adapts errors to std::result::Result.

Variants

`Matched(usize, T)`

`Failed`
