Expand description

A transform builder.

Transform builders are responsible for creating instances of Transforms, as well as describing high-level aspects of the built transform, such as the data types allowed for input events and the outputs exposed by the transform.

Required Methods§

Source

fn input_event_type(&self) -> EventType

Event type allowed as input events to this transform.

Source

fn outputs(&self) -> &[OutputDefinition<EventType>]

Event outputs exposed by this transform.

Source

fn build<'life0, 'async_trait>( &'life0 self, context: ComponentContext, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn Transform + Send>, GenericError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Builds an instance of the transform.

§Errors

If the transform can’t be built for any reason, an error is returned.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
