Struct Domain 

pub struct Domain(pub Range<f64>);

Domain or codomain of a graph.

Domain is needed for implementing DrawView for a new type of plot.

Tuple Fields

0: Range<f64>

Implementations

impl Domain

pub fn min(&self) -> f64

The smallest value of the domain.

Examples

use termplot::Domain;

let domain = Domain(-10.0..10.0);
assert_eq!(domain.min(), -10.0);

pub fn max(&self) -> f64

The largest value of the domain.

Examples

use termplot::Domain;

let domain = Domain(-10.0..10.0);
assert_eq!(domain.max(), 10.0);

pub fn range(&self) -> f64

The range of the domain as an absolute value.

Examples

use termplot::Domain;

let domain = Domain(-10.0..10.0);
assert_eq!(domain.range(), 20.0);

let domain = Domain(8.0..-8.0);
assert_eq!(domain.range(), 16.0);

pub fn iter(&self, steps: usize) -> DomainIterator

An iterator over the range where a number of steps.

For example, use this if it’s needed to compute the value of each pixel for a plot.

Examples

use termplot::{Domain};

let domain = Domain(-10.0..10.0);
let view_width = 100;

domain
    .iter(view_width)
    .for_each(|x| {
        // draw into the canvas
    });

See how plot::Graph is implemented for an in depth example.

Trait Implementations

impl Default for Domain

fn default() -> Self

Returns the “default value” for a type.
