Enum MtuDiscovery 

pub enum MtuDiscovery {
    Off,
    UpTo(u16),
}

Whether to search for a larger path MTU, and how far.

quinn’s default is to search, so an unset TransportProfile::mtu_discovery means discovery stays on. MtuDiscovery::Off is the only way to say otherwise, and it has to be expressible separately from unset: turning discovery off is a real choice for a run that wants the packet size it configured to be the packet size it gets, rather than the start of a binary search.

Variants

Off

Do not search. The packet size stays where initial_mtu put it.

UpTo(u16)

Search, but no higher than this many bytes.

Everything else about the search — interval, minimum change, black-hole cooldown — stays at quinn’s defaults.

Implementations

impl MtuDiscovery

fn to_config(self) -> Option<MtuDiscoveryConfig>

The value quinn’s mtu_discovery_config setter takes, where None genuinely disables discovery rather than meaning “unchanged”.
