Methods
impl<'a, R: Record> DuktapeReducer<'a, R>[src]
impl<'a, R: Record> DuktapeReducer<'a, R>pub fn new(repository: &'a Repository) -> Result<Self, Error>[src]
pub fn new(repository: &'a Repository) -> Result<Self, Error>pub fn reset_state(&mut self)[src]
pub fn reset_state(&mut self)Resets every reducer's state back to an empty object
Very useful for re-using the same set of reducers for multiple items, helps avoiding re-reading and re-compiling reducer functions every time.
