DataFrame-like interface for decomposition input

Required Methods

fn nrows(&self) -> usize

Get number of rows

fn ncols(&self) -> usize

Get number of columns

fn column_names(&self) -> Vec<String>

Get column names

fn to_array2(&self) -> Result<Array2<Float>>

Convert to dense Array2

fn column(&self, name: &str) -> Result<Array1<Float>>

Get column by name

fn select(&self, columns: &[String]) -> Result<Box<dyn DataFrameInterface>>

Select columns by names

Provided Methods

fn shape(&self) -> (usize, usize)

Get shape

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
