Convenience shims back to inefficient play-json formats.
Convenience shims back to inefficient play-json formats.
weePickle FromTo macros are more performant than using play-json Formats. play-json always requires going through an intermediate heavyweight AST: - JsValue boxes every type. Extra allocations. - JsObject is full of hash maps which are less efficient than struct-like classes (both cpu and memory).
