wire-desktop-core 0.1.2

Wire desktop (Electron) messenger reader — interprets the Chromium IndexedDB-over-LevelDB Dexie object stores into typed Wire records (conversations, events, users, clients) and a timeline; surfaces client-side-encrypted message payloads as unrecoverable rather than fabricating plaintext

//! Typed errors for the Wire reader.
//!
//! The load-bearing one is [`WireError::EncryptedPayloadUnrecoverable`]: Wire
//! encrypts message content client-side (Proteus), and that key is **not** held
//! in the Chromium OS Safe Storage (unlike Signal/Chrome cookie keys). So when a
//! caller asks for the plaintext of an encrypted payload we **fail loud** with a
//! typed error rather than fabricate plausible-but-wrong bytes.
