Struct aleph_bft::Signed

source ·
pub struct Signed<T, K>
where T: Signable + Index, K: Keychain,
{ /* private fields */ }
Expand description

A correctly signed object of type T.

The correctness is guaranteed by storing a (phantom) reference to the Keychain that verified the signature.

Implementations§

source§

impl<T, K> Signed<T, K>
where T: Signable + Index, K: Keychain,

source

pub fn sign(signable: T, keychain: &K) -> Signed<T, K>

Create a signed object from a signable. The index of signable must match the index of the keychain.

source

pub fn as_signable(&self) -> &T

Get a reference to the signed object.

source

pub fn into_signable(self) -> T

source

pub fn into_unchecked(self) -> UncheckedSigned<T, <K as Keychain>::Signature>

source§

impl<T, K> Signed<Indexed<T>, K>
where T: Signable, K: Keychain,

source

pub fn sign_with_index(signable: T, keychain: &K) -> Signed<Indexed<T>, K>

source§

impl<T, MK> Signed<Indexed<T>, MK>
where T: Signable, MK: MultiKeychain,

source

pub fn into_partially_multisigned( self, keychain: &MK ) -> PartiallyMultisigned<T, MK>

Transform a singly signed object into a partially multisigned consisting of just the signed object. Note that depending on the setup, it may yield a complete signature.
