Enum Event 

#[non_exhaustive]
pub enum Event {
    RxBytes(Bytes),
    TxBytes(Bytes),
    Command(Command),
    DeviceConnected,
    DeviceDisconnected {
        reason: String,
    },
    ConfigChanged(SerialConfig),
    SystemMessage(String),
    Error(Arc<Error>),
}

One unit of work that flowed through (or originated inside) a session.

#[non_exhaustive] so future variants (UserInput, Command, …) added in later issues do not break downstream code that matches.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RxBytes(Bytes)

Bytes just read from the serial device.

TxBytes(Bytes)

Bytes pending transmission to the serial device. Publishing this asks the writer task to send them.

Command(Command)

A runtime command produced by the keyboard state machine (Issue #6); subscribed by the command-handler dispatcher in Issue #7.

DeviceConnected

The session opened the device and is ready to do I/O.

DeviceDisconnected

The session lost the device (EOF, write failure, hot-unplug).

Fields

reason: String

Human-readable reason intended for logs and the status bar.

ConfigChanged(SerialConfig)

The serial configuration changed at runtime (e.g. ^T b 9600).

SystemMessage(String)

Human-readable status text emitted by the session itself (Help banner, ShowConfig, line-toggle acknowledgements, …). The terminal renderer renders these with a *** rtcom: prefix to keep them distinct from serial data; log writers (Issue #10) must drop them so they do not pollute capture files.

Error(Arc<Error>)

A non-fatal error worth surfacing to subscribers. Wrapped in Arc so the broadcast channel can clone it cheaply across receivers.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Event

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
