Struct CheckNonce

pub struct CheckNonce(/* private fields */);

The CheckNonce signed extension.

Trait Implementations

impl<T: Config> ExtrinsicParams<T> for CheckNonce

type Params = CheckNonceParams

These parameters can be provided to the constructor along with some default parameters that subxt understands, in order to help construct your ExtrinsicParams object.

fn new( _client: &ClientState<T>, params: Self::Params, ) -> Result<Self, ExtrinsicParamsError>

Construct a new instance of our ExtrinsicParams.

impl ExtrinsicParamsEncoder for CheckNonce

fn encode_extra_to(&self, v: &mut Vec<u8>)

This is expected to SCALE encode the “signed extra” parameters to some buffer that has been provided. These are the parameters which are sent along with the transaction, as well as taken into account when signing the transaction.

fn encode_additional_to(&self, _v: &mut Vec<u8>)

This is expected to SCALE encode the “additional” parameters to some buffer that has been provided. These parameters are not sent along with the transaction, but are taken into account when signing it, meaning the client and node must agree on their values.

impl<T: Config> SignedExtension<T> for CheckNonce

type Decoded = u64

The type representing the extra bytes of a signed extension. Decoding from this type should be symmetrical to the respective ExtrinsicParamsEncoder::encode_extra_to() implementation of this signed extension.

fn matches(identifier: &str, _type_id: u32, _types: &PortableRegistry) -> bool

This should return true if the signed extension matches the details given. Often, this will involve just checking that the identifier given matches that of the extension in question.
