Implementations

impl Records

pub fn new() -> Records

new creates a new Records instance

pub fn update<T>(&mut self, path: T, ts: u64) where
    T: AsRef<[u8]>, 

update increments the rank of the provided path and updates its timestamp

pub fn query<T>(&self, arguments: &[T]) -> Option<Vec<u8>> where
    T: AsRef<[u8]>, 

query matches a record from the saved records from the given arguments. The rank of a record is how many times it has been used. The match is returned based on "frecency", i.e. the highest ranked matching record is given priority, if there are multiple then the most recently accessed record with the same rank is returned.

pub fn query_and_update<T>(
    &mut self,
    arguments: &[T],
    ts: u64
) -> Option<Vec<u8>> where
    T: AsRef<[u8]>, 

query_and_update runs a query followed by an update with the result of the query.
