Trait gut::algo::partition::Partition[−][src]

pub trait Partition {
    fn partition_by_attrib<T, Src>(
        &self, 
        attrib: &str
    ) -> (Vec<usize, Global>, usize)
    where
        T: AttributeValueHash,
        Src: AttribIndex<Self>;

    fn partition_by_attrib_by_sort<T, Src>(
        &self, 
        attrib: &str

    where
        T: PartialOrd<T> + AttributeValue,
        Src: AttribIndex<Self>;
}

Required methods

Returns a partitioning by unique values of the given attribute.

The returned vector consists of a ID assigned to each Src element identifying which partition it belongs to along with the total number of partitions.

The attribute values must have type T.

If attrib doesn’t exist at the Src topology, the returned vector will consist of all zeros and the number of partitions will be 1.

If attrib doesn’t exist at the Src topology, the returned vector will consist of all zeros and the number of partitions will be 1.

This version of partition_by_attrib uses sorting to determine unique values instead of a HashMap, and therefore only relies on T being PartialOrd but not Eq and Hash.
