From 7d5696d1a9f0776f51ec20e81a413fcdcc748c4e Mon Sep 17 00:00:00 2001 From: Giacomo Travaglini Date: Tue, 8 Jan 2019 10:17:39 +0000 Subject: [PATCH] base: Make it possible to convert strings to enums The __to_number helper function defined in base/str.hh is used by unserializing code. Its purpose is to convert a string into an integral/floating point number. Since enums underlying type can only be an integer type, it makes sense to extend the helper function for enums as well. In this way it will be possible to unserialize Enums and containers of Enums without the need of casting.
