Core trait for read-only data access

This trait defines the minimal interface that any data source must provide to be usable by the TUI for rendering and display.

Required Methods

fn get_row(&self, index: usize) -> Option<Vec<String>>

Get a single row by index Returns None if the index is out of bounds

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

Get the column names/headers

fn get_row_count(&self) -> usize

Get the total number of rows

fn get_column_count(&self) -> usize

Get the total number of columns

Provided Methods

fn get_visible_rows(&self, start: usize, count: usize) -> Vec<Vec<String>>

Get multiple rows for efficient rendering This is an optimization to avoid multiple get_row calls

fn get_column_widths(&self) -> Vec<usize>

Get the display width for each column Used for rendering column widths in the TUI

fn get_cell_value(&self, row: usize, col: usize) -> Option<String>

Get a single cell value Returns None if row or column index is out of bounds

fn get_display_value(&self, row: usize, col: usize) -> String

Get a display-formatted cell value Returns empty string if indices are out of bounds

fn get_column_type(&self, _column_index: usize) -> DataType

Get the data type of a specific column This should be cached/determined at load time, not computed on each call

fn get_column_types(&self) -> Vec<DataType>

Get data types for all columns Returns a vector where index corresponds to column index
