Expand description

This trait provides the functionality to pass inputs to the monitor. You can either implement this trait for your own Datatype or use one of the predefined input methods. See MappedFactory, ArrayFactory, and VectorFactory

Required Associated Types§

Source

type Record: Send

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

Source

type Error: Into<EventFactoryError> + Send + 'static

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

Source

type CreationData: Clone + Send

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

Required Methods§

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.

Provided Methods§

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.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
