A struct sequence giving parameters of the numeric hash implementation. For more details about hashing of numeric types, see Hashing of numeric types.

attribute	explanation
`width`	width in bits used for hash values
`modulus`	prime modulus P used for numeric hash scheme
`inf`	hash value returned for a positive infinity
`nan`	hash value returned for a nan
`imag`	multiplier used for the imaginary part of a complex number
`algorithm`	name of the algorithm for hashing of str, bytes, and memoryview
`hash_bits`	internal output size of the hash algorithm
`seed_bits`	size of the seed key of the hash algorithm

New in version 3.2.

Changed in version 3.4: Added algorithm, hash_bits and seed_bits
