Struct EnvelopeFit 

pub struct EnvelopeFit { /* private fields */ }

Lower-envelope fit of offset(host) = source - host for pairs stamped on arrival, over the pairs of the last window.

Implementations

impl EnvelopeFit

pub fn new(window_ns: u64) -> Self

A fit over the last window_ns of pairs.

pub fn sixty_seconds() -> Self

The default 60 s window.

pub fn push(&mut self, host_ns: u64, source_ns: i64)

Add one pair: the source read source_ns no later than host host_ns.

pub fn reset(&mut self)

Drop every pair.

pub fn len(&self) -> usize

Pairs currently kept (at most one per host slot).

pub fn is_empty(&self) -> bool

Whether no pairs are kept.

pub fn span_ns(&self) -> u64

Host time between the oldest and the newest pair in the window.

pub fn offset_i64(&self, host_ns: u64) -> Option<i64>

Offset source - host at host time host_ns, rounded to whole ns.

pub fn to_source(&self, host_ns: u64) -> Option<i64>

Source time at host time host_ns.

pub fn skew_ppm(&self) -> f64

Skew of the source against the host, parts per million.

pub fn sigma_ns(&self) -> i64

One-sigma envelope residual, ns; -1 until ENVELOPE_SIGMA_BINS bins completed.
