From 5c33ba0aa486a2d9682e3ba8d3a6724245ac5fd3 Mon Sep 17 00:00:00 2001 From: Samuel Colvin Date: Mon, 18 Jul 2022 11:56:51 +0100 Subject: [PATCH] Self schema (#131) * generating self schema, fix #127 * allow generating self schema with older python * schema generating * remove pydantic dependency from generating schema * removing unused schema recursion checks * use build.rs, run not eval * fix to makefile * fixing schema generation * custom discriminator and fixing tests * forbid extra * fix build * fix build for 3.8 * trying to fix ci... * fix benchmarks * coverage * coverage ---
