Description
Packed, unboxed, heap-resident arrays. Suitable for performance critical use, both in terms of large data quantities and high speed.
This module is intended to be imported qualified, to avoid name clashes with Prelude functions, e.g.
import qualified Data.Text.Array as A
The names in this module resemble those in the Array family of modules, but are shorter due to the assumption of qualified naming.
Types
Immutable array type.
The Array constructor is exposed since text-1.1.1.3
Constructors
| Array | |
Fields
| |
Mutable array type, for use in the ST monad.
The MArray constructor is exposed since text-1.1.1.3
Constructors
| MArray | |
Fields

Functions
Arguments
| :: MArray s | Destination |
| -> Int | Destination offset |
| -> MArray s | Source |
| -> Int | Source offset |
| -> Int | Count |
| -> ST s () |
Copy some elements of a mutable array.
Arguments
| :: MArray s | Destination |
| -> Int | Destination offset |
| -> Array | Source |
| -> Int | Source offset |
| -> Int | First offset in destination not to copy (i.e. not length) |
| -> ST s () |
Copy some elements of an immutable array.
An empty immutable array.
Arguments
| :: Array | First |
| -> Int | Offset into first |
| -> Array | Second |
| -> Int | Offset into second |
| -> Int | Count |
| -> Bool |
Compare portions of two arrays for equality. No bounds checking is performed.
run :: (forall s. ST s (MArray s)) -> Array Source
Run an action in the ST monad and return an immutable array of its result.
run2 :: (forall s. ST s (MArray s, a)) -> (Array, a) Source
Run an action in the ST monad and return an immutable array of its result paired with whatever else the action returns.
toList :: Array -> Int -> Int -> [Word16] Source
Convert an immutable array to a list.
unsafeFreeze :: MArray s -> ST s Array Source
Freeze a mutable array. Do not mutate the MArray afterwards!
unsafeIndex :: Array -> Int -> Word16 Source
Unchecked read of an immutable array. May return garbage or crash on an out-of-bounds access.
new :: forall s. Int -> ST s (MArray s) Source
Create an uninitialized mutable array.
unsafeWrite :: MArray s -> Int -> Word16 -> ST s () Source
Unchecked write of a mutable array. May return garbage or crash on an out-of-bounds access.
