Enum MonitorMode 

#[non_exhaustive]
pub enum MonitorMode {
    None,
    Active {
        port: u16,
        echo: Option<u16>,
    },
}

Monitor-port mode resolved from the -M flag or AUTOSSH_PORT env var.

• MonitorMode::None (-M 0) — no TCP listeners; respawn ssh only on non-zero exit.
• MonitorMode::Active (-M <port> or -M <port>:<echo>) — bind a monitor-port tokio::net::TcpListener pair (or single listener when echo is supplied) and probe round-trip every AUTOSSH_POLL seconds.

Example

use rusty_autossh::MonitorMode;

// -M 0: exit-only supervision, no TCP listeners.
let none = MonitorMode::None;
assert_eq!(none, MonitorMode::default());

// -M 20000:22 single-listener mode.
let active = MonitorMode::Active { port: 20000, echo: Some(22) };
match active {
    MonitorMode::Active { port, echo } => {
        assert_eq!(port, 20000);
        assert_eq!(echo, Some(22));
    }
    _ => unreachable!(),
}

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.

None

-M 0: no monitor-port listeners; supervisor only watches child exit status.

Active

-M <port> (echo None) or -M <port>:<echo> (echo Some).

Fields

port: u16

Local monitor port.

echo: Option<u16>

Optional remote echo port. None → two local listeners (<port> + <port>+1); Some → single local listener + remote echo service.

Trait Implementations

impl Clone for MonitorMode

fn clone(&self) -> MonitorMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MonitorMode

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

Formats the value using the given formatter.

impl Default for MonitorMode

fn default() -> MonitorMode

Returns the “default value” for a type.

impl Hash for MonitorMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MonitorMode

fn eq(&self, other: &MonitorMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
