Certs: - Vendor Bambu's shared LAN-mode root CA (certs/bambu_ca2.pem, verified self-signed CA:TRUE, see certs/README.md for provenance/fingerprint). - Config gains bambu_ca_cert_path (per-printer override) and bambu_require_valid_cert (the allow/reject flag); printer::bambu::BambuTls turns those into BundledCa/Custom/Insecure. connect() doesn't perform a real handshake yet (no TLS-capable MQTT client wired in), just reports which trust mode it would use. Also reconciles a rename in flight (Printer -> GenericPrinter trait) and finishes the PrusaPrinter -> PrusaLinkPrinter/PrusaSerialPrinter split: added the missing GenericPrinter impl for PrusaSerialPrinter, fixed PrinterHandle's variant payload types, updated mod.rs's pub use list and doc comments, and updated the example to the new 5-variant shape. Verified with cargo check --all-targets (0 errors) and a full run of cargo run --example printer_polymorphism.

//! Run with: cargo run --example printer_polymorphism
|

//!
|
|
//! Demonstrates the trait+enum pattern that stands in for inheritance:
|
|
//! - `connect()` is called the same way regardless of vendor (polymorphism),
|
|
//! but each variant's `impl GenericPrinter` runs completely different
|
|
//! code (override).
|
|
//! - `dispatch_gcode()` only exists on `BambuPrinter` (extension) — you
|
|
//! have to `match` the enum back down to the concrete type to reach it,
|
|
//! which is the trade-off for not having implicit downcasting.
