I'm not sure what the size should actually be but 15 will work for now. Maybe the sso buffer should be contained in an union with one bit flag in size instead of variant that uses extra 8 bytes for type index. This patch buffs sizeof(String) from 24 bytes to 32 bytes on 64 bit. I assume this is much better version than the old which had to make allocation even for empty strings :D. --- BAN/BAN/String.cpp | 298 ++++++++++++++++++++------------------- BAN/include/BAN/String.h | 55 +++++--- 2 files changed, 186 insertions(+), 167 deletions(-) diff --git a/BAN/BAN/String.cpp b/BAN/BAN/String.cpp index 96f2693618..5f94a52bf5 100644 --- a/BAN/BAN/String.cpp +++ b/BAN/BAN/String.cpp @@ -1,102 +1,108 @@ -#include -#include -#include -#include #include -#include - -#include +#include +#include namespace BAN { String::String() { - MUST(copy_impl(""sv));
