Alpha constructs a keyspace consisting of all keys containing characters a-z, with at most `maxLength` characters.

Divvy divides the provided keyspace into N equal portions, containing disjoint keys evenly distributed across the keyspace.

Key returns the i-th unsuffixed key within the keyspace.

KeyAt returns the i-th key within the keyspace with a suffix encoding the timestamp t.

ParseSuffix returns the integer representation of the encoded suffix.

RandomPrefixInRange returns a random prefix in the range [a, b), where a and b are prefixes.

Suffix returns the test keys suffix representation of timestamp t.

SuffixLen returns the exact length of the given suffix when encoded.

WriteKey writes the i-th unsuffixed key within the keyspace to the buffer dst.

WriteKeyAt writes the i-th key within the keyspace to the buffer dst, with a suffix encoding the timestamp t suffix.

WriteSuffix writes the test keys suffix representation of timestamp t to dst, returning the number of bytes written.

Comparer is the comparer for test keys generated by this package.

MaxSuffixLen is the maximum length of a suffix generated by this package.

Keyspace describes a finite keyspace of unsuffixed test keys.
