fn into_bounds(self) -> (Option<Vec<u8>>, Option<Vec<u8>>)
Converts the prefix range representation into pair of bounds.
The conversion assumes lexicographical sorting on u8
values. For
example, PrefixRange("a")
is equivalent to "a".."b"
range. Note
that for some prefixes, either of the bounds may be None
. For
example, an empty prefix is equivalent to a full range (i.e. both bounds
being None
).
