Struct widgetry::backend_glow::Drawable[−][src]

pub struct Drawable {
    vert_array: VertexArray,
    vert_buffer: Buffer,
    elem_buffer: Buffer,
    num_indices: i32,
    gl: Rc<Context>,
}

Expand description

Geometry that’s been uploaded to the GPU once and can be quickly redrawn many times. Create by creating a GeomBatch and calling ctx.upload(batch).

Blanket Implementations

[src]

impl<T> Any for T where
T: 'static + ?Sized,

[src]

pub fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

[src]

impl<T> Borrow<T> for T where
T: ?Sized,

[src]

pub fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

[src]

impl<T> BorrowMut<T> for T where
T: ?Sized,

[src]

pub fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> Downcast for T where
T: Any,

pub fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more

pub fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more

pub fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more

pub fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s. Read more

impl<T> DowncastSync for T where
T: Any + Send + Sync,

pub fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send + 'static>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait. Read more
