Struct ChainScopedMessage 

pub struct ChainScopedMessage<M: Encode> {
    pub genesis_hash: BlockHash,
    pub nonce_or_id: u64,
    pub label: &'static [u8],
    pub expires_at: Moment,
    pub message: M,
}

Chain scoped message for signing and verifying signatures. This is used to prevent signature replay attacks across different chains.

Fields

genesis_hash: BlockHash

nonce_or_id: u64

label: &'static [u8]

expires_at: Moment

message: M

Implementations

impl<M: Encode> ChainScopedMessage<M>

pub async fn new( api: &Api, nonce_or_id: u64, label: &'static [u8], expires_at: Option<Moment>, message: M, ) -> Result<ChainScopedMessage<M>>

Create a new ChainScopedMessage unchecked.

Trait Implementations

impl<M> Encode for ChainScopedMessage<M>

where M: Encode + Encode,

fn size_hint(&self) -> usize

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

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>(&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.
