Module Tezos_test_helpers.Random_pureSource

Pseudo-random value generator.

Similar to Stdlib.Random, but with a functional interface.

Sourcetype t

Random generator state, immutable.

Initialization

Sourceval of_seed : int64 -> t

Initialize from an integer.

Sourceval split : t -> t * t

Split the state.

Sourceval next_int64 : t -> int64 * t

Generate 64 random bits, and return a new state.

Generate values

A state should be used only once to ensure the outputs are independent.

Sourceval int : t -> int -> int

Generate an int uniformly in a range [0, max).

This does not advance the state of the generator.

Sourceval bool : t -> bool

Generate a bool.

This does not advance the state of the generator.
