Struct sp_consensus_babe::OpaqueKeyOwnershipProof

pub struct OpaqueKeyOwnershipProof(_);

An opaque type used to represent the key ownership proof at the runtime API boundary. The inner value is an encoded representation of the actual key ownership proof which will be parameterized when defining the runtime. At the runtime API boundary this type is unknown and as such we keep this opaque representation, implementors of the runtime API will have to make sure that all usages of OpaqueKeyOwnershipProof refer to the same type.

Implementations

impl OpaqueKeyOwnershipProof

pub fn new(inner: Vec<u8>) -> OpaqueKeyOwnershipProof

Create a new OpaqueKeyOwnershipProof using the given encoded representation.

pub fn decode<T: Decode>(self) -> Option<T>

Try to decode this OpaqueKeyOwnershipProof into the given concrete key ownership proof type.

Trait Implementations

impl Decode for OpaqueKeyOwnershipProof

fn decode<__CodecInputEdqy: Input>(
    __codec_input_edqy: &mut __CodecInputEdqy
) -> Result<Self, Error>

Attempt to deserialise the value from input.

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

pub fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for OpaqueKeyOwnershipProof

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

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: FnOnce(&[u8]) -> R>(&self, f: F) -> R

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

pub fn size_hint(&self) -> usize
