Struct ClientWatch 

pub struct ClientWatch { /* private fields */ }

Tracks how long a host has gone without a client.

Pure bookkeeping, with the clock passed in, so the whole rule is testable without sockets or sleeping. A host calls observe each pass of its loop with the current client count.

Implementations

impl ClientWatch

pub const fn new(timeout: ClientTimeout, now: Instant) -> Self

Starts watching, with the clock already running from now.

pub const fn ever_connected(&self) -> bool

Whether any client has connected since the host started.

pub fn observe(&mut self, clients: usize, now: Instant) -> WatchState

Records the current client count and says what to do.

now is passed rather than read so the rule can be tested at any point on the clock without waiting for real time to pass.

Trait Implementations

impl Debug for ClientWatch

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

Formats the value using the given formatter.
