Struct lib::DataFrame

pub struct DataFrame { /* private fields */ }

A dataframe struct similar to pythons pandas dataframe but with less functionality and only for integers The dataframe is stored as a vector of vectors The first vector contains the column names The rest of the vectors contain the data The data is stored as a vector of vectors

Example

use numbers_rus::DataFrame;
let mut df = DataFrame::new();
df.add_column("a", &vec![1, 2, 3]);
df.add_column("b", &vec![4, 5, 6]);
df.add_column("c", &vec![7, 8, 9]);

Implementations

impl DataFrame

pub fn new() -> DataFrame

Creates a new dataframe

pub fn add_column(&mut self, name: &str, data: &Vec<i128>)

Adds a column to the dataframe

pub fn get_columns(&self) -> Vec<String>

Returns the column names

pub fn get_data(&self) -> Vec<Vec<i128>>

Returns the data

pub fn get_column(&self, name: &str) -> Result<Vec<i128>, &'static str>

Returns the column names

pub fn get_column_index(&self, name: &str) -> Result<i128, &'static str>

Returns the column names

pub fn get_column_name(&self, index: i128) -> Result<String, &'static str>

Returns the column names

pub fn get_column_count(&self) -> i128

Returns the column names

pub fn get_row_count(&self) -> usize

Returns the column names
