indexError :: Show a => (a, a) -> a -> String -> b
type IPr = (Int, Int)
data Array i e

Constructors

Array !i !i (Array# e) |

Instances

(Typeable a, Typeable b) => Typeable (Array a b)
HasBounds Array
IArray Array e
Ix i => Functor (Array i)
(Ix i, Eq e) => Eq (Array i e)
(Ix i, Ord e) => Ord (Array i e)
(Ix a, Show a, Show b) => Show (Array a b)

data STArray s i e

Mutable, boxed, non-strict arrays in the `ST` monad. The type arguments are as follows:

- `s`: the state variable argument for the `ST` type
- `i`: the index type of the array (should be an instance of `Ix`)
- `e`: the element type of the array.

Constructors

STArray !i !i (MutableArray# s e) |

Instances

HasBounds (STArray s)
MArray (STArray s) e (ST s)
(Typeable a, Typeable b, Typeable c) => Typeable (STArray a b c)
Eq (STArray s i e)
