Emitter

etl_core::ops

Struct Emitter 

Source 
pub struct Emitter<'a, OutF: RecFamily> { /* private fields */ }
Expand description

Stack-borrowed emitter handed to flat_map closures. Parameterized by the output family (a 'static tag), so user closures never name the concrete downstream stack type or the buffer lifetime. Each emit is one virtual call — confined to flat_map stages.

Implementations§

Source§

impl<OutF: RecFamily> Emitter<'_, OutF>

Source

pub fn emit<'buf>(&mut self, payload: OutF::Rec<'buf>) -> Flow

Emit one derived record, inheriting the parent’s metadata and ack handle.

Source

pub fn meta(&self) -> RecordMeta
