Random

Random number generation.

public let blob : shared () -> async Blob

public func fast(seed : Nat64) : Random

Creates a fast pseudo-random number generator using the SFC64 algorithm. This provides statistical randomness suitable for simulations and testing, but should not be used for cryptographic purposes. The seed blob's first 8 bytes are used to initialize the PRNG.

public func crypto() : AsyncRandom

Creates a random number generator suitable for cryptography using entropy from the ICP management canister with automatic resupply.

public func fromGenerator(generator : () -> Blob) : Random

public func fromAsyncGenerator(generator : () -> async* Blob) : AsyncRandom

class Random()

public let bool :

Random choice between true and false.

public let nat8 :

Random Nat8 value in the range [0, 256).

public func nat64() : Nat64

public func nat64Range(fromInclusive : Nat64, toExclusive : Nat64) : Nat64

public func natRange(fromInclusive : Nat, toExclusive : Nat) : Nat

public func intRange(fromInclusive : Int, toExclusive : Int) : Int

class AsyncRandom()

public let bool :

Random choice between true and false.

public let nat8 :

Random Nat8 value in the range [0, 256).

public func nat64() : async* Nat64

public func nat64Range(fromInclusive : Nat64, toExclusive : Nat64) : async* Nat64

public func natRange(fromInclusive : Nat, toExclusive : Nat) : async* Nat

public func intRange(fromInclusive : Int, toExclusive : Int) : async* Int
