abstract class Chunk[+O] extends Serializable

Strict, finite sequence of values that allows index-based random access of elements.

Chunks can be created from a variety of collection types using methods on the Chunk companion (e.g., Chunk.vector, Chunk.seq, Chunk.array). Additionally, the Chunk companion defines a subtype of Chunk for each primitive type, using an unboxed primitive array. To work with unboxed arrays, use methods like toBytes to convert a Chunk[Byte] to a Chunk.Bytes and then access the array directly.

The operations on Chunk are all defined strictly. For example, c.map(f).map(g).map(h) results in intermediate chunks being created (1 per call to map).
