| struct mdbx::slice |
References a data located outside the slice.
The slice is similar in many ways to std::string_view, but it implements specific capabilities and manipulates with bytes but not a characters.
Values returned from the table are valid only until a subsequent update operation, or the end of the transaction. Do not modify or free them, they commonly point into the database itself.
Key sizes must be between 0 and mdbx_env_get_maxkeysize() inclusive. The same applies to data sizes in tables with the MDBX_DUPSORT flag. Other data items can in theory be from 0 to MDBX_MAXDATASIZE bytes long.
Inherits MDBX_val.
