From 83d93084dcc661f247734186b775891c898a4696 Mon Sep 17 00:00:00 2001 From: yukinarit Date: Sun, 14 Jan 2024 19:33:42 +0900 Subject: [PATCH] pyserde is powered by beartype pyserde's strict type check is overhauled by beartype - O(1) runtime type checker. all pyserde classes now implements beartype decorator, which runs automatic validations by default.
