vector: Efficient Arrays

An efficient implementation of Int-indexed arrays (both mutable and immutable), with a powerful loop fusion optimization framework .

It is structured as follows:

Data.Vector

Boxed vectors of arbitrary types.

Data.Vector.Unboxed

Unboxed vectors with an adaptive representation based on data type families.

Data.Vector.Storable

Unboxed vectors of Storable types.

Data.Vector.Primitive

Unboxed vectors of primitive types as defined by the primitive package. Data.Vector.Unboxed is more flexible at no performance cost.

Data.Vector.Generic

Generic interface to the vector types.

There is also a (draft) tutorial on common uses of vector.

Changes in version 0.7

• New functions for freezing, copying and thawing vectors: freeze, thaw, unsafeThaw and clone

• newWith and newUnsafeWith on mutable vectors replaced by replicate

• New function: concat

• New function for safe indexing: (!?)

• Monoid instances for all vector types

• Significant recycling and fusion improvements

• Bug fixes

• Support for GHC 7.0

Flags

Automatic Flags

Name	Description	Default
boundschecks	Enable bounds checking	Enabled
unsafechecks	Enable bounds checking in unsafe operations at the cost of a significant performance penalty	Disabled
