SipHash‐1‐3‐UJ based hasher for the coins cache and related coins containers.
Synopsis
Declared in <coins.h>
class SaltedCoinsCacheHasher;Description
Retained entries identify real transaction outputs, so their keys contain computed txids. Missing‐input lookups may contain arbitrary claimed prevouts, but FetchCoin() immediately erases their temporary entries when the backend lookup fails, so non‐hash keys cannot accumulate.
The assumeutxo loader assumes snapshot txids are valid while loading and verifies the complete snapshot's content hash before activation.
Hash values are process‐local and must not be persisted, serialized, or compared across processes.
Having the hash noexcept lets libstdc++ recalculate it during rehash instead of storing it in each node.
