Values
namespace Minilib.Monad.Random
random_I64_range
Type: [m : Minilib.Monad.Random::MonadRandom] Std::I64 -> Std::I64 -> m Std::I64
random_I64_range(begin, end) generates a random integer r
such that begin <= r && r < end.
if begin >= end, it panicks.
random_U16
Type: [m : Minilib.Monad.Random::MonadRandom] m Std::U16
random_U16 generates a random integer of U8.
random_U32
Type: [m : Minilib.Monad.Random::MonadRandom] m Std::U32
random_U32 generates a random integer of U32.
random_U8
Type: [m : Minilib.Monad.Random::MonadRandom] m Std::U8
random_U8 generates a random integer of U8.
random_array
Type: [m : Minilib.Monad.Random::MonadRandom] Std::I64 -> m a -> m (Std::Array a)
random_array(size, random) generates a random array of specified size
by performing random repeatedly.
shuffle
Type: [m : Minilib.Monad.Random::MonadRandom] Std::Array a -> m (Std::Array a)
Shuffles an array.
namespace Minilib.Monad.Random::MonadRandomIF
random_U64
Type: [m : Minilib.Monad.Random::MonadRandomIF] m Std::U64
random_U64 generates a random integer of U64.
random_bytes
Type: [m : Minilib.Monad.Random::MonadRandomIF] Std::I64 -> m (Std::Array Std::U8)
random_bytes generates random bytes of specified size.
Types and aliases
Traits and aliases
namespace Minilib.Monad.Random
trait [m : *->*] m : MonadRandomIF
A trait for a monad that generates random numbers every time.
method random_U64
Type: m Std::U64
random_U64 generates a random integer of U64.
method random_bytes
Type: Std::I64 -> m (Std::Array Std::U8)
random_bytes generates random bytes of specified size.
Trait implementations
impl [rg : Minilib.Trait.Rng::Rng, lf1 : Minilib.Trait.Lifter::Lifter, lf2 : Minilib.Trait.Lifter::Lifter, m : Std::Monad] Minilib.Monad.State::StateT rg m : Minilib.Monad.Random::MonadRandomIF
An implementation of MonadRandomIF for the StateT monad.
A state monad StateT rg m can be used as a MonadRandom,
if the state rg implements Rng trait, and the target monad m is compatible to RngResult.
The result type of Rng is lifted to the target monad m by the lifter.
