Struct PrimitiveStyleBuilder

pub struct PrimitiveStyleBuilder<C>
where
    C: PixelColor,
{ /* private fields */ }

Primitive style builder.

Use this builder to create PrimitiveStyles. If any properties on the builder are omitted, the value will remain at its default value.

The primitive_style! macro can also be used to create PrimitiveStyles, but with a shorter syntax. See the primitive_style! documentation for examples.

Examples

Build a style with configured stroke and fill

This example builds a style for a circle with a 3px red stroke and a solid green fill. The circle is centered at (20, 20) with a radius of 10px.

use embedded_graphics::{
    egtext,
    pixelcolor::Rgb565,
    prelude::*,
    primitives::Circle,
    style::{PrimitiveStyle, PrimitiveStyleBuilder},
};

let style: PrimitiveStyle<Rgb565> = PrimitiveStyleBuilder::new()
    .stroke_color(Rgb565::RED)
    .stroke_width(3)
    .fill_color(Rgb565::GREEN)
    .build();

let circle = Circle::new(Point::new(20, 20), 10).into_styled(style);

Build a style with stroke and no fill

This example builds a style for a rectangle with a 1px red stroke. Because .fill_color() is not called, the fill color remains the default value of None (i.e. transparent).

use embedded_graphics::{
    egtext,
    pixelcolor::Rgb565,
    prelude::*,
    primitives::Rectangle,
    style::{PrimitiveStyle, PrimitiveStyleBuilder},
};

let style: PrimitiveStyle<Rgb565> = PrimitiveStyleBuilder::new()
    .stroke_color(Rgb565::RED)
    .stroke_width(1)
    .build();

let rectangle = Rectangle::new(Point::new(20, 20), Point::new(40, 30)).into_styled(style);

Implementations

Trait Implementations

impl<C> Clone for PrimitiveStyleBuilder<C>

where C: PixelColor + Clone,

fn clone(&self) -> PrimitiveStyleBuilder<C>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<C> Debug for PrimitiveStyleBuilder<C>

where C: PixelColor + Debug,

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

Formats the value using the given formatter.

impl<C> Default for PrimitiveStyleBuilder<C>

where C: PixelColor + Default,

fn default() -> PrimitiveStyleBuilder<C>

Returns the “default value” for a type.

impl<C> Hash for PrimitiveStyleBuilder<C>

where C: PixelColor + Hash,

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<C> Ord for PrimitiveStyleBuilder<C>

where C: PixelColor + Ord,

fn cmp(&self, other: &PrimitiveStyleBuilder<C>) -> 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,

Restrict a value to a certain interval.

impl<C> PartialEq for PrimitiveStyleBuilder<C>

where C: PixelColor + PartialEq,

fn eq(&self, other: &PrimitiveStyleBuilder<C>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl<C> PartialOrd for PrimitiveStyleBuilder<C>

where C: PixelColor + PartialOrd,

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl<C> Copy for PrimitiveStyleBuilder<C>

where C: PixelColor + Copy,

impl<C> Eq for PrimitiveStyleBuilder<C>

where C: PixelColor + Eq,

impl<C> StructuralPartialEq for PrimitiveStyleBuilder<C>

where C: PixelColor,

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
