Enum TopN 

pub enum TopN {
    First(usize),
    Last(usize),
}

Controls how many rows to take from a sorted dataframe.

Used with SortedDataFrame::topn to retrieve a fixed number of rows from the top or bottom of a sorted result.

Variants

First(usize)

Take the first n rows (smallest values).

Last(usize)

Take the last n rows (largest values).

Trait Implementations

impl Clone for TopN

fn clone(&self) -> TopN

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TopN

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TopN

fn eq(&self, other: &TopN) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
