ArraySchema

class ArraySchema<T>(val elementSchema: FateSchema<T>) : FateSchema<Array<T>>

A schema for arrays of T, written as a 4-byte element count followed by each element.

List, Set and Collection fields use the same format, so a List<Double> field has the same bytes as a Double[] field. Kotlin's primitive arrays have their own schemas (DoubleArraySchema and friends) that write the same bytes without boxing.

Binary format

The schema:

[4 bytes: tag] [element schema blob]

An encoded array:

[4 bytes: element count N] [element1] [element2] ... [elementN]

Constructors
