Module `Private_state_enums.State`Source

Sourcetype t = Random.State.t

same as BatRandom.State

The type of PRNG states.

Sourceval make : int array -> t

Create a new state and initialize it with the given seed.

Sourceval make_self_init : unit -> t

Create a new state and initialize it with a system-dependent low-entropy seed.

Sourceval copy : t -> t

Return a copy of the given state.

Sourceval bits : t -> int

Sourceval int : t -> int -> int

Sourceval int32 : t -> Int32.t -> Int32.t

Sourceval nativeint : t -> Nativeint.t -> Nativeint.t

Sourceval int64 : t -> Int64.t -> Int64.t

Sourceval float : t -> float -> float

Sourceval bool : t -> bool

Sourceval char : t -> char

Sourceval enum_bits : t -> unit -> int BatEnum.t

A copy of the input state is made to start these generators; the input state is not modified. This means that two enums constructed from the same state will produce the same value sequence.

Sourceval enum_int : t -> int -> int BatEnum.t

Sourceval enum_bool : t -> unit -> bool BatEnum.t

Sourceval enum_float : t -> float -> float BatEnum.t

Sourceval enum_int32 : t -> Int32.t -> Int32.t BatEnum.t

Sourceval enum_int64 : t -> Int64.t -> Int64.t BatEnum.t

Sourceval enum_nativeint : t -> Nativeint.t -> Nativeint.t BatEnum.t

Sourceval enum_char : t -> unit -> char BatEnum.t

Sourceval perturb : t -> t

perturb s returns a new state based on the given state that is, in a sense, the hash of the input state. This new state should be quite different from the input.
