Available on crate feature marsh only.

Version and capability of protocol version. This message can be requested with MAV_CMD_REQUEST_MESSAGE and is used as part of the handshaking to establish which MAVLink version should be used on the network. Every node should respond to a request for PROTOCOL_VERSION to enable the handshaking. Library implementers should consider adding this into the default decoding state machine to allow the protocol core to respond directly.

Implementations

impl PROTOCOL_VERSION_DATA

pub const ENCODED_LEN: usize = 22usize

pub const DEFAULT: Self

Trait Implementations

impl Clone for PROTOCOL_VERSION_DATA

fn clone(&self) -> PROTOCOL_VERSION_DATA

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PROTOCOL_VERSION_DATA

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PROTOCOL_VERSION_DATA

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PROTOCOL_VERSION_DATA

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl MessageData for PROTOCOL_VERSION_DATA

const ID: u32 = 300u32

const NAME: &'static str = "PROTOCOL_VERSION"

const EXTRA_CRC: u8 = 217u8

const ENCODED_LEN: usize = 22usize

type Message = MavMessage

fn deser(_version: MavlinkVersion, __input: &[u8]) -> Result<Self, ParserError>

Errors

fn ser(&self, version: MavlinkVersion, bytes: &mut [u8]) -> usize

Panics

impl PartialEq for PROTOCOL_VERSION_DATA

fn eq(&self, other: &PROTOCOL_VERSION_DATA) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PROTOCOL_VERSION_DATA

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
