Struct embedded_graphics::primitives::line::Line

pub struct Line {
    pub start: Point,
    pub end: Point,
}

Line primitive

Examples

Create some lines with different styles

use embedded_graphics::{
    pixelcolor::Rgb565, prelude::*, primitives::{Line, PrimitiveStyle},
};

// Red 1 pixel wide line from (50, 20) to (60, 35)
Line::new(Point::new(50, 20), Point::new(60, 35))
    .into_styled(PrimitiveStyle::with_stroke(Rgb565::RED, 1))
    .draw(&mut display)?;

// Green 10 pixel wide line with translation applied
Line::new(Point::new(50, 20), Point::new(60, 35))
    .translate(Point::new(-30, 10))
    .into_styled(PrimitiveStyle::with_stroke(Rgb565::GREEN, 10))
    .draw(&mut display)?;

Fields

Implementations

impl Line

pub const fn new(start: Point, end: Point) -> Self

Creates a line between two points.

pub const fn with_delta(start: Point, delta: Point) -> Self

Creates a line with a start point and a delta vector.

Examples

use embedded_graphics::{prelude::*, primitives::Line};

let line = Line::with_delta(Point::new(10, 20), Point::new(20, -20));

pub fn midpoint(&self) -> Point

Compute the midpoint of the line.

pub fn delta(&self) -> Point

Compute the delta (end - start) of the line.

Trait Implementations

impl Clone for Line

fn clone(&self) -> Line

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Line

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Line

fn default() -> Line

Returns the “default value” for a type.

impl Dimensions for Line

fn bounding_box(&self) -> Rectangle

Returns the bounding box.

impl Hash for Line

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given [Hasher].

impl Ord for Line

fn cmp(&self, other: &Line) -> Ordering

This method returns an [Ordering] between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Line

fn eq(&self, other: &Line) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Line

fn partial_cmp(&self, other: &Line) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl PointsIter for Line

type Iter = Points

Iterator over all points inside the primitive.

fn points(&self) -> Self::Iter

Returns an iterator over all points inside the primitive.

impl Primitive for Line

fn into_styled<S>(self, style: S) -> Styled<Self, S>

where Self: Sized,

Converts this primitive into a Styled.

impl<C: PixelColor> StyledDimensions<PrimitiveStyle<C>> for Line

fn styled_bounding_box(&self, style: &PrimitiveStyle<C>) -> Rectangle

Returns the bounding box using the given style.

impl<C: PixelColor> StyledDrawable<PrimitiveStyle<C>> for Line

type Color = C

Color type.

type Output = ()

Output type.

fn draw_styled<D>( &self, style: &PrimitiveStyle<C>, target: &mut D, ) -> Result<Self::Output, D::Error>

where D: DrawTarget<Color = C>,

Draws the primitive using the given style.

impl Transform for Line

fn translate(&self, by: Point) -> Self

Translate the line from its current position to a new position by (x, y) pixels, returning a new Line. For a mutating transform, see translate_mut.

let line = Line::new(Point::new(5, 10), Point::new(15, 20));
let moved = line.translate(Point::new(10, 10));

assert_eq!(moved.start, Point::new(15, 20));
assert_eq!(moved.end, Point::new(25, 30));

fn translate_mut(&mut self, by: Point) -> &mut Self

Translate the line from its current position to a new position by (x, y) pixels.

let mut line = Line::new(Point::new(5, 10), Point::new(15, 20));
line.translate_mut(Point::new(10, 10));

assert_eq!(line.start, Point::new(15, 20));
