Struct aleph_bft::Indexed

pub struct Indexed<T>
where
    T: Signable,
{ /* private fields */ }

A pair consistsing of signable data and a NodeIndex.

This is a wrapper used for signing data which does not implement the Index trait. If a node with an index i needs to sign some data signable which does not implement the Index trait, it should use the Signed::sign_with_index method which will use this wrapper transparently. Note that in the implementation of Signable for Indexed<T>, the hash is the hash of the underlying data T. Therefore, instances of the type Signed<Indexed<T>, MK> can be aggregated into Multisigned<T, MK>

Trait Implementations

impl<T> Clone for Indexed<T>

where T: Clone + Signable,

fn clone(&self) -> Indexed<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Indexed<T>

where T: Debug + Signable,

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

Formats the value using the given formatter.

impl<T> Decode for Indexed<T>

where T: Signable + Decode,

fn decode<__CodecInputEdqy>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Indexed<T>, Error>

where __CodecInputEdqy: Input,

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<T> Encode for Indexed<T>

where T: Signable + 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,

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where 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> Hash for Indexed<T>

where T: Hash + Signable,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> Index for Indexed<T>

where T: Signable,

fn index(&self) -> NodeIndex

impl<T> PartialEq for Indexed<T>

where T: PartialEq + Signable,

fn eq(&self, other: &Indexed<T>) -> 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.

impl<T> Signable for Indexed<T>

where T: Signable,

type Hash = <T as Signable>::Hash

fn hash(&self) -> <Indexed<T> as Signable>::Hash

Return a hash for signing.
