fz::QuantizerConfig Struct Reference

#include <quantizer.h>

Public Attributes
float	abs_error_bound
	Absolute EB after mode conversion (0 for REL).
float	user_error_bound
	Original user-specified EB.
float	value_base
	value_range (NOA); 0 for ABS/REL.
uint32_t	quant_radius
	Quantization radius.
uint32_t	num_elements
	Total element count.
uint32_t	outlier_count
	Actual number of outliers.
DataType	input_type
	Original input type (1B).
DataType	code_type
	Quantization code type (1B).
uint8_t	eb_mode
	ErrorBoundMode cast to uint8_t.
uint8_t	zigzag_codes
	1 if ABS/NOA codes are zigzag-encoded.
float	outlier_threshold
	ABS/NOA: |x| >= threshold → forced outlier (inf = disabled).
uint8_t	inplace_outliers
	1 if outliers are encoded in-place in the codes array.
uint8_t	_pad [3]
	Alignment padding — must be zero.

Detailed Description

Serialized quantizer configuration stored in FZMBufferEntry.stage_config. Written by serializeHeader(); read back by deserializeHeader(). 36 bytes — fits within the 128-byte FZM_STAGE_CONFIG_SIZE limit.
