Struct FixBuilder 

pub struct FixBuilder { /* private fields */ }

A VesselState under construction, built up one reading at a time.

Readings arrive as separate calls to its setters regardless of source – a Signal K delta, a parsed NMEA 0183 sentence, a replayed passage – and this type only tracks whether enough have arrived for a complete state. It has no knowledge of the source protocol.

Implementations

impl FixBuilder

pub fn new() -> Self

Nothing heard yet.

pub fn set_position(&mut self, position: Position)

Records a position. Only a position update marks a fix as fresh; course and speed updates alone must not reset the age of a stalled position.

pub fn set_course_over_ground(&mut self, deg: f64)

Records course over ground, degrees true.

pub fn set_speed_over_ground(&mut self, kn: f64)

Records speed over ground, knots.

pub fn set_heading(&mut self, deg: f64)

Records heading, degrees true. Never required – see VesselState::heading_deg.

pub fn complete(self) -> Option<VesselState>

A complete state, if enough has arrived to build one.

Heading may be missing – a vessel without a compass has no heading line. Position, course and speed are required; there is no meaningful default for any of them.
