Trait mavio::protocol::Sign

pub trait Sign {
    // Required methods
    fn reset(&mut self);
    fn digest(&mut self, bytes: &[u8]);
    fn produce(&self) -> SignatureValue;
}

Interface for MAVLink 2 frames signing algorithm.

An implementor of Sign should be capable to calculate sha256_48, a MAVLink 2 specific hashing algorithm similar to regular sha256 except that only first 48 bits are considered.

Links

• Signer wraps and implementor of Sign and capable of signing and validating frames.
• Values calculated by implementors of Sign are stored in Signature struct as value.
• Signature specification format in MAVLink docs.

Required Methods

fn reset(&mut self)

Reset inner state of a signer.

Used by caller to ensure that signer’s inner state does not have any digested data.

fn digest(&mut self, bytes: &[u8])

Adds value to digest.

Caller can invoke Sign::digest multiple times. Passing data as several sequential chunks is the same as calling digest with the whole data at once.

fn produce(&self) -> SignatureValue

Produces MAVLink 2 signature from the internal state.
