ComputeResult computes the full measurement result from parsed TOR data and peaks.

NewScanner creates a new Scanner that reads RTCM3 frames from r.

ParseExtensionFields parses a buffer of zero or more concatenated extension fields per RFC 7822 §7.5. The buffer must contain only extension fields; a

Start launches the subscription timers and exit on expire

buildPayloadWithType creates a payload with the given RTCM3 message type encoded in the first 12 bits, padded to the specified total length.

setbitu sets n bits (MSB-first) at bit offset pos.

Communicate sends the management the packet, parses response into something usable

EnableTimestamps enables timestamps on the socket based on requested type

Err returns the first non-EOF error encountered by the Scanner.

generic function to check value against some thresholds

copy all key-values between maps

chrony reports all float measures in seconds, while NTP and this tool operate ms

BestSample finds a sample which took the least time to be read; the logic is loosely based on sysoff_estimate from ptp4l sysoff.c

Frame returns the most recently scanned frame. It is only valid after Scan returns true.

GetOperation returns int operation extracted from REMOp 8bit word

MakeVnMode composes uint8 with version and mode bits set
