sourcemeta::jsonbinpack::BOUNDED_MULTIPLE_8BITS_ENUM_FIXED Struct Reference

The encoding consists of the integer value divided by the multiplier, minus the ceil of minimum divided by the multiplier, encoded as an 8-bit fixed-length unsigned integer. More...

#include <runtime_plan.h>

Public Attributes
const std::int64_t	minimum
	The inclusive minimum value.
const std::int64_t	maximum
	The inclusive maximum value.
const std::uint64_t	multiplier
	The multiplier value.

Detailed Description

The encoding consists of the integer value divided by the multiplier, minus the ceil of minimum divided by the multiplier, encoded as an 8-bit fixed-length unsigned integer.

Options

Option	Type	Description
minimum	int	The inclusive minimum value
maximum	int	The inclusive maximum value
multiplier	uint	The multiplier value

Conditions

Condition	Description
value >= minimum	The input value must be greater than or equal to the minimum
value <= maximum	The input value must be less than or equal to the maximum
value % multiplier == 0	The input value must be divisible by the multiplier
floor(maximum / multiplier) - ceil(minimum / multiplier) < 2 ** 8	The divided range must be representable in 8 bits

Examples

Given the input value 15, where the minimum is 1, the maximum is 19, and the multiplier is 5, the encoding results in the 8-bit unsigned integer 2:
