Struct aleph_bft_rmc::Signed

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

A correctly signed object of type T.

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

Implementations

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

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.

pub fn as_signable(&self) -> &T

Get a reference to the signed object.

pub fn into_signable(self) -> T

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

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

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

Create a signed object from a signable. The index is added based on the index of the keychain.

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

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.

Returns the fixed encoded size of the type.

impl<T, K> Encode for Signed<T, K>where T: Signable + Index, K: Keychain, UncheckedSigned<T, <K as Keychain>::Signature>: Encode,

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )where __CodecOutputEdqy: Output + ?Sized,

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T, K> From<Signed<T, K>> for UncheckedSigned<T, <K as Keychain>::Signature>where T: Signable + Index, K: Keychain,

fn from(signed: Signed<T, K>) -> UncheckedSigned<T, <K as Keychain>::Signature>

fn eq(&self, other: &Signed<T, K>) -> bool

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

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

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