Struct TransformBuilder 

Source 
pub struct TransformBuilder<I, O, R: Spawn + 'static> { /* private fields */ }
Expand description

Configures a single-input transform pipeline.

Created by RecordRegistrar::transform_raw(). Use .map() for stateless transforms or .with_state() for stateful transforms.

Implementations§

Source§

impl<I, O, R> TransformBuilder<I, O, R>
where I: Send + Sync + Clone + Debug + 'static, O: Send + Sync + Clone + Debug + 'static, R: Spawn + 'static,

Source

pub fn map<F>(self, f: F) -> TransformPipeline<I, O, R>
where F: Fn(&I) -> Option<O> + Send + Sync + 'static,

Stateless 1:1 map. Returning None skips output for this input value.

Source

pub fn with_state<S: Send + Sync + 'static>( self, initial: S, ) -> StatefulTransformBuilder<I, O, S, R>

Begin configuring a stateful transform. S is the user-defined state type.
