The fixed NTPv4 header.

Fields

leap: LeapIndicator

version: u8

mode: Mode

stratum: u8

poll: i8

precision: i8

root_delay: NtpShort

root_dispersion: NtpShort

reference_id: [u8; 4]

reference_ts: NtpTimestamp

origin_ts: NtpTimestamp

receive_ts: NtpTimestamp

transmit_ts: NtpTimestamp

Implementations

impl NtpPacket

pub fn client_request(version: u8, transmit_ts: NtpTimestamp) -> Self

A mode-3 client request. The caller supplies transmit_ts, which SHOULD be an unpredictable nonce rather than the real clock (BCP: it is echoed back as origin_ts and is the only spoofing defence an unauthenticated client has).

pub fn parse(buf: &[u8]) -> Result<NtpPacket, ParseError>

Parse the 48-byte header. Trailing bytes (extension fields / legacy MAC) are left to extension_fields.

pub fn write(&self, buf: &mut [u8; 48])

Serialize the header into a 48-byte buffer.

pub fn to_bytes(&self) -> [u8; 48]
