pub enum ProtocolError {
    RequestTooShort {
        received: usize,
    },
    UnexpectedMode {
        mode: u8,
    },
    UnsupportedVersion {
        version: u8,
    },
    ZeroTransmitTimestamp,
    NoExtensionFields,
    Other(String),
}

NTP protocol validation errors for incoming client requests.

These correspond to the checks performed in server_common::validation per RFC 5905 Section 8.

Variants

RequestTooShort

Fields

received: usize

Number of bytes received.

UnexpectedMode

Fields

mode: u8

The mode value received.

UnsupportedVersion

Unsupported NTP version in request.

Fields

version: u8

The version value received.

ZeroTransmitTimestamp

Client transmit timestamp is zero.

NoExtensionFields

Request has no extension fields (expected for NTS).

Other(String)

Generic protocol error.

Trait Implementations

impl Clone for ProtocolError

fn clone(&self) -> ProtocolError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProtocolError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ProtocolError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ProtocolError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ProtocolError> for NtpServerError

fn from(err: ProtocolError) -> NtpServerError

Converts to this type from the input type.
