Struct dunge::Context

pub struct Context { /* private fields */ }

The application context.

Implementations

impl Context

pub fn window(&self) -> &Window

Returns the window.

pub fn plan_to_close(&self)

Plans the main loop to close.

Calling this function dosn’t guarantee closing. It triggers the close_requested function in the Loop, which can handle the closing event.

pub fn size(&self) -> (u32, u32)

Returns the canvas size.

pub fn set_limits(&mut self, limits: Limits)

Sets context’s Limits.

pub fn set_frame_parameters(&mut self, params: FrameParameters)

Sets context’s frame parameters via FrameParameters struct.

No effect if pixel_size in FrameParameters is 0.

pub fn create_layer<V, T>(&mut self) -> LayerHandle<V, T>where V: Vertex, T: Topology,

Creates a new layer with default parameters.

This is a shortcut for context.create_layer_with_parameters().build(). See create_layer_with_parameters for more info.

pub fn create_layer_with_parameters<V, T>( &mut self ) -> ParametersBuilder<'_, V, T>

Creates a layer builder with custom parameters.

pub fn delete_layer<V, T>( &mut self, handle: LayerHandle<V, T> ) -> Result<(), Error>

Deletes the layer.

Errors

See Error for detailed info.

pub fn create_texture(&mut self, data: TextureData<'_>) -> TextureHandle

Creates a new texture.

pub fn update_texture( &mut self, handle: TextureHandle, data: TextureData<'_> ) -> Result<(), Error>

Updates the texture.

Errors

See Error for detailed info.

pub fn delete_texture(&mut self, handle: TextureHandle) -> Result<(), Error>

Deletes the texture.

Errors

See Error for detailed info.

pub fn create_instances<I>(&mut self, data: I) -> InstanceHandlewhere I: IntoIterator, I::Item: IntoTransform, <I::Item as IntoTransform>::IntoQuat: IntoQuat,

Creates new instances.

pub fn update_instances<I>( &mut self, handle: InstanceHandle, data: I ) -> Result<(), Error>where I: IntoIterator, I::Item: IntoTransform, <I::Item as IntoTransform>::IntoQuat: IntoQuat,

Updates instances.

Errors

See Error for detailed info.

pub fn delete_instances(&mut self, handle: InstanceHandle) -> Result<(), Error>

Deletes instances.

Errors

See Error for detailed info.

pub fn create_mesh<V, T>( &mut self, data: &MeshData<'_, V, T> ) -> MeshHandle<V, T>where V: Vertex, T: Topology,

Creates a new mesh.

pub fn update_mesh<V, T>( &mut self, handle: MeshHandle<V, T>, data: &MeshData<'_, V, T> ) -> Result<(), Error>where V: Vertex, T: Topology,

Updates the mesh.

Errors

See Error for detailed info.

pub fn delete_mesh<V, T>( &mut self, handle: MeshHandle<V, T> ) -> Result<(), Error>

Deletes the mesh.

Errors

pub fn create_view<P>(&mut self, view: View<P>) -> ViewHandlewhere P: IntoProjection,

Creates a new view.

pub fn update_view<P>( &mut self, handle: ViewHandle, view: View<P> ) -> Result<(), Error>where P: IntoProjection,

Updates the view.

Errors

See Error for detailed info.

pub fn delete_view(&mut self, handle: ViewHandle) -> Result<(), Error>

Deletes the view.
