Struct safe_network::messaging::DataAuthority

pub struct DataAuthority { /* fields omitted */ }

Verified authority of a network peer.

Values of this type constitute a proof that the signature is valid for a particular payload. This is made possible by performing verification in all possible constructors of the type.

Implementations

impl DataAuthority

pub fn verify(
    public_key: PublicKey,
    signature: Signature,
    payload: &impl AsRef<[u8]>
) -> Result<Self>

Verify that payload has requester’s authority.

This verifies that the owner of public_key (e.g. the holder of the corresponding private key) created the signature by signing the payload with theor private key. When this is true, we say the payload has data authority.

pub fn public_key(&self) -> &PublicKey

Get the signer’s public key.

pub fn to_signed(&self) -> DataSigned

Create a DataSigned from this authority by cloning the fields.

Since DataAuthority cannot be serialized, it’s sometimes necessary to convert back to an unverified signature. Prefer DataSigned::from if you don’t need to retain the DataAuthority, as this won’t clone the fields.

Trait Implementations

impl Clone for DataAuthority

fn clone(&self) -> DataAuthority

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataAuthority

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

Formats the value using the given formatter.

impl From<DataAuthority> for DataSigned

A DataAuthority can be converted back to a DataSigned, losing the ‘proof’ of validity.

fn from(signed: DataAuthority) -> Self

Performs the conversion.

impl PartialEq<DataAuthority> for DataAuthority

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
