pub struct FilterOperator<D> where
    D: Data + for<'a> Deserialize<'a>, 
{ /* private fields */ }
Expand description

Filters an incoming stream of type D, retaining messages in the stream that the provided condition function evaluates to true when applied.

Example

The below example shows how to use a FilterOperator to keep only messages > 10 in an incoming stream of usize messages, and send them.

// Add the mapping function as an argument to the operator via the OperatorConfig.
let filter_config = OperatorConfig::new().name("FilterOperator");
let filter_stream = erdos::connect_one_in_one_out(
    || -> FilterOperator<usize> { FilterOperator::new(|a: &usize| -> bool { a > &10 }) },
    || {},
    filter_config,
    &source_stream,
);
