Struct calamine::Range

pub struct Range { /* fields omitted */ }

A struct which represents a squared selection of cells

Methods

impl Range

fn new(start: (u32, u32), end: (u32, u32)) -> Range

Creates a new range

fn get_position(&self) -> (u32, u32)

Get top left cell position (row, column)

fn width(&self) -> usize

Get column width

fn height(&self) -> usize

Get column width

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

Get size

fn is_empty(&self) -> bool

Is range empty

fn set_value(&mut self, pos: (u32, u32), value: DataType) -> Result<()>

Set inner value

Panics if indexes are out of range bounds

Examples

use calamine::{Range, DataType};

let mut range = Range::new((0, 0), (5, 2));
assert_eq!(range.get_value(2, 1), &DataType::Empty);
range.set_value((2, 1), DataType::Float(1.0)).expect("Could not set value");
assert_eq!(range.get_value(2, 1), &DataType::Float(1.0));

fn get_value(&self, i: u32, j: u32) -> &DataType

Get cell value

Panics if indexes are out of range bounds

fn rows(&self) -> Rows

Get an iterator over inner rows

Examples

use calamine::Range;

let range = Range::new((0, 0), (5, 2));
// with rows item row: &[DataType]
assert_eq!(range.rows().flat_map(|row| row).count(), 18);

Trait Implementations

impl Debug for Range

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for Range

fn default() -> Range

Returns the "default value" for a type.

impl Clone for Range

fn clone(&self) -> Range

Returns a copy of the value.

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

Performs copy-assignment from source.
