Struct SplitEmitter 

pub struct SplitEmitter<'a> { /* private fields */ }

Stack-borrowed emitter handed to a route closure. emit routes one derived record to the branch named by a SplitBranch<F> handle; a record that emits to no branch triggers the split’s unmatched policy. One Any downcast per emit, no per-call name lookup.

Implementations

impl SplitEmitter<'_>

pub fn emit<'buf, F: RecFamily + 'static>( &mut self, handle: SplitBranch<F>, row: F::Rec<'buf>, )

Route one derived record to handle’s branch, inheriting the parent’s metadata and acknowledgment handle. Emitting to no branch (returning from the closure without any emit) invokes the unmatched policy. Once a branch of this split holds a fatal, every later emit in the payload is dropped until the chain drains it.

Panics

Panics if handle’s index lies past this split’s branches, or its record family does not match the branch at that index. A handle minted by another split’s builder whose index and family match a branch of this split routes to that branch without a panic.

pub fn meta(&self) -> RecordMeta

The parent record’s metadata.
