Enum pixel_widgets::draw::Command

pub enum Command {
    Nop,
    Clip {
        scissor: Rectangle,
    },
    Colored {
        offset: usize,
        count: usize,
    },
    Textured {
        texture: usize,
        offset: usize,
        count: usize,
    },
}

A draw Command that is to be translated to a draw command specific to the backend

Variants

Nop

Do nothing. Appending a Nop to another command will flush the other command.

Clip

Sets a new scissor rect, which is used to confine geometry to a certain area on screen.

Fields of Clip

scissor: Rectangle

The scissor rectangle

Colored

Draw a list of vertices without an active texture

Fields of Colored

offset: usize

Offset in vertices from the start of the vertex buffer

count: usize

The number of vertices to draw

Textured

Draw a list of vertices with the active texture denoted by it’s index

Fields of Textured

texture: usize

Texture id to be used

offset: usize

Offset in vertices from the start of the vertex buffer

count: usize

The number of vertices to draw

Implementations

impl Command

pub fn append(&mut self, command: Command) -> Option<Command>

Append another Command to this Command. If the Commands can be chained together the Command is extended and None is returned, but if the Commands can not be chained the new command is returned again.

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Command

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

Formats the value using the given formatter.
