Summary: Expose the inverse of ToString(hex=true) on Slice: Slice::DecodeHex Refactor the other implementation of to/from hex in ldb_cmd.h to use the Slice version (Difference between the 2 is whether 0x is expected/produced in front of the hex string or not) Eliminated support for invalid odd length hex string - this is now invalid instead of having 1/2 byte set Added (inverse of HexToString) test for LDBCommand::StringToHex which also indirectly tests Slice::ToString(true) After moving the original implementation from ldb_cmd.h, updated it to much simpler/efficient version (originally/inspired from https://github.com/facebook/wdt/blob/master/util/EncryptionUtils.cpp#L140-L169 ) Test Plan: run tests Reviewers: uddipta, sdong Reviewed By: sdong Subscribers: andrewkr, dhruba Differential Revision: https://reviews.facebook.net/D56121
