Struct TimeWindowTransformer 

pub struct TimeWindowTransformer<T: Debug + Clone + Send + Sync + 'static> {
    pub duration: Duration,
    pub config: TransformerConfig<T>,
    pub _phantom: PhantomData<T>,
}

A transformer that creates time-based windows of items from a stream.

This transformer groups consecutive items into windows based on time duration, producing vectors of items as windows are created based on time intervals.

Fields

duration: Duration

The duration of each window.

config: TransformerConfig<T>

Configuration for the transformer, including error handling strategy.

_phantom: PhantomData<T>

Phantom data to track the type parameter.

Implementations

impl<T: Debug + Clone + Send + Sync + 'static> TimeWindowTransformer<T>

pub fn new(duration: Duration) -> Self

Creates a new TimeWindowTransformer with the given window duration.

Arguments

• duration - The duration of each window.

pub fn with_error_strategy(self, strategy: ErrorStrategy<T>) -> Self

Sets the error handling strategy for this transformer.

Arguments

• strategy - The error handling strategy to use.

pub fn with_name(self, name: String) -> Self

Sets the name for this transformer.

Arguments

• name - The name to assign to this transformer.
