[APMSP-1583] Fix hash in BytesString #767

Closed VianneyRuhlmann closed 3 days ago

VianneyRuhlmann commented 3 days ago

What does this PR do?

BytesString derives Hash from Bytes which hashes the string as a &[u8]. BytesString also implements Borrow<str> which requires both types to have the same hash. The issue is that [u8] and str do not have compatible hash functions, so BytesString should use str hash implementation.

This PR also adds:

Motivation

Hash is required to handle meta hashmap in spans
