Source

pub struct EmptyFactory<T: Send>(/* private fields */);

Expand description

A dummy event factory, that never produces a value for an input stream.

impl<T: Send> EventFactory for EmptyFactory<T>

Source §

type CreationData = ()

Arbitrary type of the data provided to the input source at creation time.

Source §

type Error = Infallible

The error type returned by the input source on IO errors or parsing issues.

Source §

type Record = T

The type from which an event is generated by the input source.

Source §

fn try_new( map: HashMap<String, InputReference>, _setup_data: Self::CreationData, ) -> Result<(Self, Vec<String>), EventFactoryError>

Construction the input for only a subset of the required input streams. Enables the combination of multiple Input implementors into one. The returned Vector contains the names of the input streams that can be served by this input. The constructed input should return Value::None for all inputs that are unknown to it.

Source §

fn get_event(&self, _rec: Self::Record) -> Result<Event, EventFactoryError>

This function converts a record to an event.

Source §

fn new( map: HashMap<String, InputReference>, setup_data: Self::CreationData, ) -> Result<Self, EventFactoryError>

Creates a new input source from a HashMap mapping the names of the inputs in the specification to their position in the event.
