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). In contrast, a chunk can be lifted to a segment (via toSegment) to get arbitrary operator fusion.
