Package tuple provides a layer for encoding and decoding multi-element tuples into keys usable by FoundationDB.

FirstGreaterOrEqual returns the KeySelector specifying the lexigraphically least key present in the database which is lexigraphically greater than or equal to the given key.

FirstGreaterThan returns the KeySelector specifying the lexigraphically least key present in the database which is lexigraphically strictly greater than the given key.

Returns the API version that has been selected through APIVersion or MustAPIVersion.

LastLessOrEqual returns the KeySelector specifying the lexigraphically greatest key present in the database which is lexigraphically less than or equal to the given key.

LastLessThan returns the KeySelector specifying the lexigraphically greatest key present in the database which is lexigraphically strictly less than the given key.

Printable returns a human readable version of a byte array.

KeySelector represents a description of a key in a FoundationDB database.

A KeyConvertible can be converted to a FoundationDB Key.

A Selectable can be converted to a FoundationDB KeySelector.

Key represents a FoundationDB key, a lexicographically-ordered sequence of bytes.
