Struct Signer 

pub struct Signer { /* private fields */ }

Signs outgoing v2 frames with a shared key.

A signer holds the key, the link id it stamps, and a monotonically increasing timestamp. Seed the timestamp from a field clock with timestamp_from_unix_micros where one is available; without a clock, any strictly increasing seed works, since the receiver only requires that timestamps rise.

Implementations

impl Signer

pub fn new(key: [u8; 32], link_id: u8, timestamp: u64) -> Self

Creates a signer for a key, a link id, and a starting timestamp.

Arguments

• key - the 32-byte shared secret.
• link_id - the id of the link this signer stamps on its frames.
• timestamp - the first timestamp to use, in 10-microsecond ticks since the MAVLink epoch.

Returns

The signer.

pub fn sign( &mut self, header: Header, msgid: u32, payload: &[u8], crc_extra: u8, ) -> Result<Frame>

Builds and signs a v2 frame for a message.

The frame is assembled with the signed flag set so the flag is covered by the checksum, then the signature block is filled and the signer’s timestamp advanced.

Arguments

• header - the addressing fields to stamp on the frame.
• msgid - the 24-bit message id.
• payload - the serialized message payload.
• crc_extra - the CRC_EXTRA seed for msgid.

Returns

The signed frame, ready to send.

Errors

Returns MavlinkError::PayloadTooLong if the payload does not fit a frame.

pub fn link_id(&self) -> u8

Returns the link id this signer stamps.

Returns

The link id.

Trait Implementations

impl Clone for Signer

fn clone(&self) -> Signer

Returns a duplicate of the value.

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

Performs copy-assignment from source.
