tech.datatype

A Clojure library for efficient manipulation of contiguous mutable containers of primitive datatypes.

A nice post explaining more is here.

Generalized efficient manipulations of sequences of primitive datatype. Includes specializations for java arrays, array views (subsection of an array) and nio buffers. There are specializations to allow implementations to provide efficient full typed copy functions when the types can be ascertained.

Generic operations include:

1. datatype of this sequence.
2. Writing to, reading from.
3. Construction.
4. Efficient mutable copy from one sequence to another.

Examples

(:require [tech.datatype.core :as dtype])

(let [ary (dtype/make-array-of-type :float32 (range 10))
      buf (dtype/make-array-of-type :float64 10)]
  ;;copy starting at position 2 of ary into position 4 of buf 4 elements
  (dtype/copy! ary 2 buf 4 4))
  ;;buf now has [0 0 0 0 2 3 4 5 0 0]
