twtb.logic.shared.db.sharing_message

Makes possible sharing messages between client and bot.

Because almost all IDs in Telegram are unique only to one bot. Here, we firstly send message to the shared chat, from where bot reforwards message to the end users.

This is the only way to share message ID that I found.

Functions

hash_with_fnv64(→ str)

FNV-1a 64-bit hash implementation.

hash_with_fnv64(string: str) → str

FNV-1a 64-bit hash implementation.

It is a fast non-cryptographic hash function, which is good for us to transform the message data into short form.
