Struct combee::dataframe::GroupedDataFrame

pub struct GroupedDataFrame<'a, D: Clone + DeserializeOwned + Serialize, I: Eq + Hash + Clone, F>where
    F: Fn(&D) -> I,{ /* private fields */ }

A Grouped DataFrame, you can use a aggregator function to get a DataFrame.

Implementations

impl<'a, D: Clone + DeserializeOwned + Serialize, I: Eq + Clone + Hash, F> GroupedDataFrame<'a, D, I, F>where F: Fn(&D) -> I,

pub fn agg<S: Clone + DeserializeOwned + Serialize, G>( &self, aggregator: G ) -> DataFrame<S>where G: Fn(&I, &Group<'_, D>) -> S,

Aggregates a GroupedDataFrame in a new DataFrame using a aggregator function.
