void	process_hash (const simulation::EventEmitterInterface< simulation::Poseidon2HashEvent >::Container &hash_events, TraceContainer &trace)
	Processes the hash events for the Poseidon2 hash function. It populates the columns for the poseidon2_hash sub-trace. It generates a row per permutation call, (ca. 1/3 of number of inputs to hash).
void	process_permutation (const simulation::EventEmitterInterface< simulation::Poseidon2PermutationEvent >::Container &perm_events, TraceContainer &trace)
	Processes the permutation events for the Poseidon2 permutation function. It populates the columns for the poseidon2_perm sub-trace. It generates exactly 1 row per invocation.
void	process_permutation_with_memory (const simulation::EventEmitterInterface< simulation::Poseidon2PermutationMemoryEvent >::Container &perm_mem_events, TraceContainer &trace)
	Processes the events for the Poseidon2 memory-aware permutation function. It populates the columns for the poseidon2_perm_mem sub-trace. It generates exactly 1 row per invocation.

process_hash()

void bb::avm2::tracegen::Poseidon2TraceBuilder::process_hash	(	const simulation::EventEmitterInterface< simulation::Poseidon2HashEvent >::Container &	hash_events,
		TraceContainer &	trace
	)

Processes the hash events for the Poseidon2 hash function. It populates the columns for the poseidon2_hash sub-trace. It generates a row per permutation call, (ca. 1/3 of number of inputs to hash).

Parameters

hash_events	The container of hash events to process.
trace	The trace container.

Definition at line 105 of file poseidon2_trace.cpp.

process_permutation()

void bb::avm2::tracegen::Poseidon2TraceBuilder::process_permutation	(	const simulation::EventEmitterInterface< simulation::Poseidon2PermutationEvent >::Container &	perm_events,
		TraceContainer &	trace
	)

Processes the permutation events for the Poseidon2 permutation function. It populates the columns for the poseidon2_perm sub-trace. It generates exactly 1 row per invocation.

Parameters

perm_events	The container of permutation events to process.
trace	The trace container.

Definition at line 173 of file poseidon2_trace.cpp.

process_permutation_with_memory()

void bb::avm2::tracegen::Poseidon2TraceBuilder::process_permutation_with_memory	(	const simulation::EventEmitterInterface< simulation::Poseidon2PermutationMemoryEvent >::Container &	perm_mem_events,
		TraceContainer &	trace
	)

Processes the events for the Poseidon2 memory-aware permutation function. It populates the columns for the poseidon2_perm_mem sub-trace. It generates exactly 1 row per invocation.

Parameters

perm_mem_events	The container of the memory-aware permutation events to process.
trace	The trace container.
