Struct SplitTransformer 

pub struct SplitTransformer<F, T>
where
    F: Send + 'static,
    T: Debug + Clone + Send + Sync + 'static,
{
    pub predicate: F,
    pub _phantom: PhantomData<T>,
    pub config: TransformerConfig<Vec<T>>,
}

A transformer that splits a stream of items into groups based on a predicate.

This transformer groups consecutive items where the predicate returns true into separate vectors, effectively splitting the stream at points where the predicate returns false.

Fields

predicate: F

The predicate function used to determine split points.

_phantom: PhantomData<T>

Phantom data to track the item type parameter.

config: TransformerConfig<Vec<T>>

Configuration for the transformer, including error handling strategy.

Implementations

impl<F, T> SplitTransformer<F, T>

where F: FnMut(&T) -> bool + Send + Clone + 'static, T: Debug + Clone + Send + Sync + 'static,

pub fn new(predicate: F) -> Self

Arguments

• predicate - The function to use for determining split points.

pub fn with_error_strategy(self, strategy: ErrorStrategy<Vec<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.
