Enum Command

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

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

§scissor: Rectangle

The scissor rectangle

§

Colored

Draw a list of vertices without an active texture

Fields

§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

§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§

Source§

impl Command

Source

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.
