LazyTProtocol

trait LazyTProtocol extends TProtocol

An extension to the TProtocol to enable lazy reading

Three main classes of operations are intended to be enabled here:

1) Enable caching of a backing Array[Byte] so we can serialize quickly what we just deserialized if unchanged. 2) Enabling deferred string decoding, since string decoding is an expensive operation if we don't need the string large savings can be had avoiding this for all strings in our deserialization path. 3) Optional fields require boxing + allocations during deserialization for primitive types, this stores the offset to those types instead, doing a lazy instantiation of the Option when the field is first accessed.

    Take a segment of an Array[Byte] and presume it is already encoded for this transport and just copy it down.

    This is useful if we have a cached set of bytes used when deserializing a field or struct
