Enum ServerError 

pub enum ServerError {
    RandomSource {
        reason: String,
    },
    TokenExhausted {
        attempts: u32,
    },
    ReplyEncoding {
        source: ProtoError,
    },
}

An internal server failure.

This type deliberately does not describe rejected traffic. Malformed, unauthenticated, unsupported and policy-refused datagrams are not errors: the protocol defines no rejection response, so they are answered with silence and reported as Ok(None) from ServerCore::handle_datagram. An inbound ProtoError never reaches a caller — that is the whole point of the admission boundary, which turns hostile UDP into a dropped datagram rather than a failure.

Every variant here is instead something wrong on this side, where the server could not do its job for a request it had already accepted.

Variants

RandomSource

The operating system’s random source failed, so no session token could be drawn.

Fields

reason: String

TokenExhausted

No unique non-zero token was found within the retry budget.

Each attempt drew a fresh value and rejected it as zero or as a collision with a live session. With a working random source this is vanishingly unlikely; it exists so token allocation cannot spin forever on a degenerate source.

Fields

attempts: u32

ReplyEncoding

A reply the server itself constructed could not be encoded.

The ProtoError here always describes server-generated bytes, never anything a peer sent.

Fields

source: ProtoError

Trait Implementations

impl Eq for ServerError

impl Error for ServerError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
