👎Deprecated since 0.2.0: please use the rand-unique crate instead

The configuration for RandomSequence, a random unique sequence generator.

These variables define the entire sequence and should not be modified with the exception of seed_base and seed_offset during initialisation.

The builder defines the internal properties of the sequence, and serialization includes all of the properties to preserve the sequence between crate versions which may change the fixed values between minor versions.

Crate versioning will bump:

• Minor version: when the hard coded parameters are updated in favour of better ones. It is safe to serialize the RandomSequenceBuilder between minor versions.
• Major version: when the sequence generation logic fundamentally changes the sequence, meaning it would be potentially unsafe to serialize the RandomSequenceBuilder between major crate version changes.

Fields

seed_base: T

👎Deprecated since 0.2.0: please use the rand-unique crate instead

The seed for the the start index.

seed_offset: T

👎Deprecated since 0.2.0: please use the rand-unique crate instead

The seed for the offsetting addition.

init_base: T

👎Deprecated since 0.2.0: please use the rand-unique crate instead

A value used as an xor during initialisation for start_index = f(seed_base, init_base) to deterministically pseudo-randomise it.

init_offset: T

👎Deprecated since 0.2.0: please use the rand-unique crate instead

A value used as an xor during initialisation for offset = f(seed_offset, init_offset) to deterministically pseudo-randomise it.

prime: T

👎Deprecated since 0.2.0: please use the rand-unique crate instead

Should be the largest prime number that fits in type T and satisfied prime = 3 mod 4.

intermediate_xor: T

👎Deprecated since 0.2.0: please use the rand-unique crate instead

A value that provides some noise from the xor to generate a pseudo-uniform distribution.
