Hashes.hpp

#pragma once
 
// Qt-aware adapters over ossia::hash (rapidhash). Centralises the
// QString / QByteArray hashing pattern so cache keys across the gfx
// pipeline produce the same stable values without each call site
// re-deriving the trick of hashing the raw character buffer.
//
// All hashes here delegate to ossia::hash_bytes, which dispatches
// to the appropriate rapidhash tier (Nano / Micro / full) based on
// size. Use these — not qHash, not std::hash<QString> — for any
// in-memory cache key in this plugin.
