Enum RefusalCause 

#[non_exhaustive]
pub enum RefusalCause {
    GlobalCap,
    ListenerCap,
    SourceCap,
    LaneReserve,
    Gate(u16),
    Session,
    Busy,

}

Why a connection was refused.

assert_eq!(net_io::RefusalCause::SourceCap.as_str(), "source_cap");

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.

GlobalCap

The global connection cap was reached.

ListenerCap

The listener’s connection cap was reached.

SourceCap

The per-source concurrency cap was reached.

LaneReserve

The lane’s reservation was used up.

Gate(u16)

The gate refused, with its code.

Session

The session factory refused.

Busy

The blocking driver had no free worker.

DoorClosed

The door was closed.

Shed

The control line shed this lane.

Lockdown

The control line is in lockdown and the listener does not allow it.
