fz::FusedSideOutput Struct Reference

#include <fusion_registry.h>

Public Attributes
Stage *	producer
	the group member that owns this output port
int	output_index
	which of the producer's output ports this is
void *	d_ptr
	pre-allocated buffer for the port
size_t	capacity
	its allocated size in bytes
size_t	size
	OUT: bytes the runner wrote (DAG sets the buffer size from this)
FusedAuxOutputDecl	declaration
	semantic identity/sizing rule, if declared

Detailed Description

A group member's escaping output port — a side output (e.g. an outlier list) the fused kernel produces in addition to the main archive. It may be a pipeline leaf or continue through staged consumers outside the specialized region. The runner writes d_ptr and reports the bytes it wrote in size; the DAG then sizes the boundary buffer. Empty for the common single-output case.
