Struct sp_finality_grandpa::OpaqueKeyOwnershipProof

[+] Show declaration

pub struct OpaqueKeyOwnershipProof(_);

[−] Expand description

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.
