pub fn new() -> Self

pub fn validate(&mut self) -> Result<(), Error>

pub fn add( &mut self, filter: &Filter, name: &str, args: &str, ) -> Result<Context, Error>

pub fn get(&mut self, name: &str) -> Option<Context>

pub fn dump(&self) -> String

pub fn input(&mut self, name: &str, pad: usize) -> Result<Parser<'_>, Error>
