Struct zng_view :: extensions :: ViewExtensions Copy item path

impl ViewExtensions

pub fn register<E: ViewExtension>( &mut self, ext: impl FnOnce(ApiExtensionId) -> E, ) -> &mut Self

Register an extension with the ID that will be assigned to it.

The ID is useful for error messages.

§Panics

Panics if the name is already registered.

pub fn id(&self, name: &ApiExtensionName) -> Option<ApiExtensionId>

Returns the extension ID.

pub fn command_raw( &mut self, name: impl Into<ApiExtensionName>, handler: impl FnMut(ApiExtensionPayload, ApiExtensionId) -> ApiExtensionPayload + Send + 'static, ) -> &mut Self

Register a command extension with custom encoded messages.

The handler receives the request payload and it’s own ID to be used in error messages.

pub fn command<I: DeserializeOwned, O: Serialize>( &mut self, name: impl Into<ApiExtensionName>, handler: impl FnMut(I, ApiExtensionId) -> O + Send + 'static, ) -> &mut Self

Register a command extension.

The handler receives the deserialized request payload and it’s own ID to be used in error messages.

pub fn window<E: WindowExtension>( &mut self, name: impl Into<ApiExtensionName>, new: impl FnMut(ApiExtensionId) -> E + Send + 'static, ) -> &mut Self

Register a window extension with its own ID.

pub fn renderer<E: RendererExtension>( &mut self, name: impl Into<ApiExtensionName>, new: impl FnMut(ApiExtensionId) -> E + Send + 'static, ) -> &mut Self

Register a renderer extension with its own ID.

pub fn append(&mut self, other: ViewExtensions)

Add other to self.

Auto Trait Implementations§

impl !UnwindSafe for ViewExtensions

Blanket Implementations§

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

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

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

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

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

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

Mutably borrows from an owned value. Read more

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

fn into_any(self: Box<T>) -> Box<dyn Any>

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.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

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

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.

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.

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T> Instrument for T

fn instrument(self, span: Span) -> Instrumented<Self>

Instruments this type with the provided [Span], returning an Instrumented wrapper. Read more

fn in_current_span(self) -> Instrumented<Self>

Instruments this type with the current Span, returning an Instrumented wrapper. Read more

impl<T, U> Into for T
where U: From<T>,

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

impl<T> IntoEither for T

fn into_either(self, into_left: bool) -> Either<Self, Self>

Converts self into a Left variant of Either<Self, Self> if into_left is true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more

fn into_either_with<F>(self, into_left: F) -> Either<Self, Self>
where F: FnOnce(&Self) -> bool,

Converts self into a Left variant of Either<Self, Self> if into_left(&self) returns true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more
