Struct spirit_tokio::net::limits::Limits

#[non_exhaustive]pub struct Limits {
    pub error_sleep: Duration,
    pub max_conn: Option<usize>,
}

An implementation of ListenLimits that reads the limits from configuration.

Fields

• error-sleep: The back-off time when non-fatal error happens, in human readable form. Defaults to 100ms if not present.
• max-conn: Maximum number of parallel connections on this listener. Defaults to no limit (well, to usize::max_value() / 8 - 1, actually, for technical reasons, but that should be effectively no limit).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

error_sleep: Duration

How long to wait before trying again after an error.

Some errors when accepting are simply ignored (eg. the connection was closed by the other side before we had time to accept it). Some others (eg. too many open files) put the acceptor into a sleep before it tries again, in the hope the situation will have improved by then.

Defaults to 100ms if not set.

max_conn: Option<usize>

Maximum number of connections per one listener.

If it is reached, more connections will not be accepted until some of the old ones are terminated.

Defaults to implementation limits if not set (2^31 - 1 on 32bit systems, 2^63 - 1 on 64bit systems), which is likely higher than what the OS can effectively handle ‒ so you can assume that if not set, there's no limit.
