}

Domain events produced by the SSH engine, config loaders, and the update checker. Background tasks send these over a dedicated channel; the frontend wraps them into its own event stream.

Variants

MetricsUpdate(HostId, Metrics)

SSH metrics received from a background task.

HostStatusChanged(HostId, ConnectionStatus)

Connection status changed for a host (reported by metrics poller).

FileTransferProgress(TransferId, u64, u64)

File transfer progress: (transfer_id, bytes_done, bytes_total).

Error(String)

An error message surfaced to the user.

HostsLoaded(Vec<Host>)

Host list loaded from disk / SSH config in a background task.

SnippetsLoaded(Vec<Snippet>)

Snippet list loaded from disk in a background task.

SnippetResult

Result of executing a snippet or quick-execute command on one host. output is Ok(stdout) or Err(error_message).

Fields

host_name: String

snippet_name: String

output: Result<String, String>

FileDirListed

Remote directory listing completed.

Fields

path: String

entries: Vec<FileEntry>

LocalDirListed

Local directory listing completed.

Fields

path: String

entries: Vec<FileEntry>

SftpConnected

SFTP session successfully established.

Fields

host_name: String

SftpManagerReady

SFTP manager ready with established connection (contains SftpManager handle).

Fields

host_name: String

manager: Box<SftpManager>

SftpDisconnected

SFTP session closed or failed.

Fields

reason: String

FilePreviewReady

Preview bytes available for a file.

Fields

path: String

content: String

SftpOpDone

A mutating SFTP operation (delete, mkdir, rename, upload, download) finished.

Fields

result: Result<(), String>

PtyOutput(SessionId)

A PTY session produced output. The bytes are already parsed into the session’s Arc<Mutex<vt100::Parser>>; this event is a lightweight render-nudge so the main loop can update has_activity state without copying bulk output data through the channel.

PtyExited(SessionId)

The PTY child process exited (reader thread reached EOF or I/O error).

DiscoveryQuickScanDone(HostId, Vec<DetectedService>)

Quick scan completed for a host, services detected.

DiscoveryFailed(HostId, String)

Discovery failed for a host with an error message.

KeySetupProgress(HostId, KeySetupStep)

Progress update from key setup (host_id, current step, total steps).

KeySetupComplete(HostId, PathBuf)

Key setup completed successfully (host_id, private_key_path).

KeySetupFailed(HostId, String)

Key setup failed with an error (host_id, error_message).

KeySetupRollback(HostId, String)

Emergency rollback was triggered (host_id, rollback_result).

UpdateAvailable(UpdateInfo)

A newer release was found on GitHub at startup.

UpdateInstalled(Result<(), String>)

A self-update finished — Ok on success, Err with a message on failure.
