lanyard.flight.VehicleState.1.1¶
Consolidated vehicle state, published by the flight controller at 50 Hz.
| Full name | lanyard.flight.VehicleState |
| Version | 1.1 |
| Kind | Message |
| Fixed port ID | 6210 |
| Least supported transport | CAN FD |
Wire layout¶
| Section | Extent (bytes) | Max serialized (bytes) |
|---|---|---|
| Message | 128 | 53 |
A sealed type reports its extent as its exact serialized size; a delimited type reports the declared @extent, which bounds what a reader must be prepared to receive.
Definition¶
# Consolidated vehicle state, published by the flight controller at 50
# Hz.
#
# LEAST SUPPORTED TRANSPORT: CAN FD.
#
# VERSIONING -- THIS IS THE NON-BREAKING CHANGE EXAMPLE.
#
# Relative to VehicleState.1.0 this definition appends one field and
# changes nothing else. That is permissible without a major version bump
# because:
#
# 1. The type is delimited (@extent), so every serialized value is
# preceded by a length header and a reader may skip a tail it does
# not recognize.
# 2. The extent is unchanged, so a 1.0 reader's buffer is still large
# enough for a 1.1 message.
# 3. Existing fields keep their order, type, and meaning, so a 1.0
# reader decoding a 1.1 message gets correct values for everything
# it knows about and ignores height_above_takeoff.
# 4. A 1.1 reader decoding a 1.0 message sees a short tail and leaves
# height_above_takeoff at its zero value -- which is why an
# appended field must have a sane interpretation when absent.
#
# Because it is compatible in both directions, 1.1 keeps the same fixed
# port identifier as 1.0: both minor versions share port 6210 and
# coexist on the same subject.

# Consolidated vehicle state, published by the flight controller at 50
# Hz.
#
# LEAST SUPPORTED TRANSPORT: CAN FD.
#
# VERSIONING -- THIS IS THE NON-BREAKING CHANGE EXAMPLE.
#
# Relative to VehicleState.1.0 this definition appends one field and
# changes nothing else. That is permissible without a major version bump
# because:
#
# 1. The type is delimited (@extent), so every serialized value is
# preceded by a length header and a reader may skip a tail it does
# not recognize.
# 2. The extent is unchanged, so a 1.0 reader's buffer is still large
# enough for a 1.1 message.
# 3. Existing fields keep their order, type, and meaning, so a 1.0
# reader decoding a 1.1 message gets correct values for everything
# it knows about and ignores height_above_takeoff.
# 4. A 1.1 reader decoding a 1.0 message sees a short tail and leaves
# height_above_takeoff at its zero value -- which is why an
# appended field must have a sane interpretation when absent.
#
# Because it is compatible in both directions, 1.1 keeps the same fixed
# port identifier as 1.0: both minor versions share port 6210 and
# coexist on the same subject.
