Enum peg_runtime::RuleResult

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

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.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
