Enum NetError

#[non_exhaustive]pub enum NetError {
    Busy,
    Dns(DnsError),
    Message(&'static str),
    Msg(String),
    ParseInt(ParseIntError),
    NoConnections,
    Proto(ProtoError),
    Io(Arc<Error>),
    Timeout,
    QueryCaseMismatch,
}

Expand description

The error type for network protocol errors (UDP, TCP, QUIC, H2, H3)

Variants (Non-exhaustive)§

This enum is marked as 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.

Busy

The underlying resource is too busy

This is a signal that an internal resource is too busy. The intended action should be tried again, ideally after waiting for a little while for the situation to improve. Alternatively, the action could be tried on another resource (for example, in a name server pool).

Dns(DnsError)

Semantic DNS errors

Message(&'static str)

An error with an arbitrary message, referenced as &’static str

Msg(String)

An error with an arbitrary message, stored as String

ParseInt(ParseIntError)

Unable to parse header value as number

NoConnections

No connections available

Proto(ProtoError)

Protocol error from higher layers

Io(Arc<Error>)

An error got returned from IO

Timeout

A request timed out

QueryCaseMismatch

Case randomization is enabled, and a server did not echo a query name back with the same case.
