Data.Bytes.Mutable

If you are interested in sub-arrays of MutableByteArrays (e.g. writing quicksort), it would be grossly inefficient to make a copy of the sub-array. On the other hand, it'd be really annoying to track limit indices by hand.

This module defines the MutableBytes type which exposes a standard array interface for a sub-arrays without copying and without manual index manipulation. For immutable arrays, see Data.Bytes.

Types

1 declaration

datadata MutableBytes s

A slice of a MutableByteArray.

Filtering

2 declarations

valuetakeWhile

:: PrimMonad m
=> Word8 -> m Bool
-> MutableBytes (PrimState m)
-> m (MutableBytes (PrimState m))

Take bytes while the predicate is true, aliasing the argument array.

valuedropWhile

:: PrimMonad m
=> Word8 -> m Bool
-> MutableBytes (PrimState m)
-> m (MutableBytes (PrimState m))

Drop bytes while the predicate is true, aliasing the argument array.

Unsafe Slicing

2 declarations

valueunsafeTake :: Int -> MutableBytes s -> MutableBytes s

Take the first n bytes from the argument, aliasing it.

valueunsafeDrop :: Int -> MutableBytes s -> MutableBytes s

Drop the first n bytes from the argument, aliasing it. The new length will be len - n.

Conversion

1 declaration

valuefromMutableByteArray

Create a slice of MutableBytes that spans the entire argument array. This aliases the argument.
