Module ntp 

NTPv4 packet codec (RFC 5905) with extension-field iteration (RFC 7822).

Every entry point is a parse-constructor returning Result; nothing here can panic on untrusted bytes (the fuzz targets in fuzz/ hold this line).

Structs

ExtensionField

One RFC 7822 extension field: type, and its value bytes (header excluded).

ExtensionIter

NtpPacket

The fixed NTPv4 header.

NtpShort

32-bit NTP short format: 16.16 fixed-point seconds (root delay / dispersion).

NtpTimestamp

64-bit NTP timestamp: 32.32 fixed-point seconds since the era epoch.

Enums

LeapIndicator

Mode

ParseError

Trailer

What follows the fixed header.

Constants

HEADER_LEN

Length of the fixed NTPv4 header.

UNIX_EPOCH_OFFSET

Seconds between the NTP era-0 epoch (1900-01-01) and the Unix epoch (1970-01-01).

Functions

extension_fields

Iterate whatever follows the 48-byte header. Malformed input can never panic: anything that does not parse as an extension field is yielded once as Trailer::Opaque and iteration ends.

offset_delay

Offset/delay from the four client-exchange timestamps (RFC 5905 §8), all in seconds on any common timescale. Returns (offset, delay); offset is seconds to ADD to the local clock.
