tech.datatype

tech.datatype is for efficient manipulation of containers of data.

A nice (slightly out of date) post explaining more is here.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
5. Sparse buffer support
6. n-dimensional tensor support
7. Functional math support

design documenation is here.

Examples

user> (require '[tech.v2.datatype :as dtype])
:tech.resource.gc Reference thread starting
nil
user> (let [ary (dtype/make-container :java-array :float32 (range 10))
            buf (dtype/make-container :native-buffer :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]
        (dtype/->vector buf))
