Struct nannou_egui::Renderer

pub struct Renderer { /* fields omitted */ }

A wrapper around all necessary state for rendering a Egui to a single texture (often a window texture).

For targeting more than one window, users should construct a Egui for each.

Implementations

impl Renderer

pub fn new(
    device: &Device,
    target_format: TextureFormat,
    target_msaa_samples: u32
) -> Self

Create a new Renderer from its parts.

The device must be the same that was used to create the queue to which the Renderers render passes will be submitted.

The target_format and target_msaa_samples should describe the target texture to which the Egui will be rendered.

pub fn from_window(window: &Window) -> Self

Construct a Renderer ready for drawing to the given window.

pub fn encode_render_pass(
    &mut self,
    context: &CtxRef,
    device: &Device,
    queue: &Queue,
    encoder: &mut CommandEncoder,
    dst_size_pixels: [u32; 2],
    dst_scale_factor: f32,
    dst_texture: &TextureView
) -> Result<(), BackendError>

Encode a render pass for drawing the given context’s texture to the given dst_texture.

pub fn draw_to_frame(
    &mut self,
    context: &CtxRef,
    frame: &Frame<'_>
) -> Result<(), BackendError>

Encodes a render pass for drawing the given context’s texture to the given frame.
