Function zerotrie::reader::take_value

pub(crate) fn take_value(trie: &mut &[u8]) -> Option<usize>

Steps one node into the trie if the head node is a value node, returning the value. If the head node is not a value node, no change is made.

The input-output argument trie starts at the original trie and ends pointing to the sub-trie with the value node removed.
