[Tarantool-patches] [PATCH v3 5/9] box, datetime: messagepack support for datetime
Timur Safin
tsafin at tarantool.org
Mon Aug 2 03:41:01 MSK 2021
Serialize datetime_t as newly introduced MP_EXT type.
It saves 1 required integer field and upto 2 optional
unsigned fields in very compact fashion.
- secs is required field;
- but nsec, offset are both optional;
* json, yaml serialization formats, lua output mode
supported;
* exported symbols for datetime messagepack size calculations
so they are available for usage on Lua side.
Part of #5941
Part of #5946
