Struct LinkOptions 

#[non_exhaustive]
pub struct LinkOptions {
    pub rate_limit_factor: f64,
    pub send_timeout: Duration,
    pub request_timeout: Duration,
}

Tunables for a single link.

The type is #[non_exhaustive] because a link acquires tunables as it hardens — two arrived in one release — and this crate is released ahead of every consumer of it. Without the attribute each new tunable would be a major bump cascading through dig-gossip and everything downstream of it; with it, adding one is additive.

The cost is that consumers cannot name the type in a struct expression at all — not even with ..Default::default(), which Rust also forbids for a #[non_exhaustive] struct. Start from Default and assign the fields you care about:

use std::time::Duration;
use dig_peer_protocol::LinkOptions;

let mut options = LinkOptions::default();
options.request_timeout = Duration::from_secs(5);

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.

rate_limit_factor: f64

Scales every outbound rate-limit budget. 1.0 is the nominal Chia allowance.

send_timeout: Duration

How long DigLink::send_message may wait for rate-limit budget before giving up.

Only a deferrable refusal waits at all — an oversized message is refused immediately, since no amount of waiting makes it fit.

request_timeout: Duration

How long a correlated request waits for its reply before erroring.

Without a deadline a silent or wedged peer leaves the caller pending forever, which is indistinguishable from a lost future.
