pub enum ViewportsState {
    Fixed {
        data: Vec<(Viewport, Scissor)>,
    },

List of viewports and scissors that are used when creating a graphics pipeline object.

Note that the number of viewports and scissors must be the same.

Variants

Fixed

Fields

data: Vec<(Viewport, Scissor)>

State of the viewports and scissors.

The state is known in advance.

DynamicViewports

Fields

scissors: Vec<Scissor>

State of the scissors.

The state of scissors is known in advance, but the state of viewports is dynamic and will bet set when drawing.

Note that the number of viewports and scissors must be the same.

DynamicScissors

Fields

viewports: Vec<Viewport>

State of the viewports

The state of viewports is known in advance, but the state of scissors is dynamic and will bet set when drawing.

Note that the number of viewports and scissors must be the same.

Dynamic

Fields

num: u32

Number of viewports and scissors.

The state of both the viewports and scissors is dynamic and will be set when drawing.
