pub struct ExtrinsicMetadata<T: Form = MetaForm> {
    pub ty: T::Type,
    pub version: u8,
    pub signed_extensions: Vec<SignedExtensionMetadata<T>>,
}

Metadata of the extrinsic used by the runtime.

Fields

ty: T::Type

version: u8

Extrinsic version.

signed_extensions: Vec<SignedExtensionMetadata<T>>

The signed extensions in the order they appear in the extrinsic.

Trait Implementations

impl<T: Clone + Form> Clone for ExtrinsicMetadata<T>where
    T::Type: Clone,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Form> Debug for ExtrinsicMetadata<T>where
    T::Type: Debug,

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

Formats the value using the given formatter.

impl<T: Form> Decode for ExtrinsicMetadata<T>where
    T::Type: Decode,
    Vec<SignedExtensionMetadata<T>>: Decode,

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

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: Form> Encode for ExtrinsicMetadata<T>where
    T::Type: Encode,
    Vec<SignedExtensionMetadata<T>>: 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, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere
    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 IntoPortable for ExtrinsicMetadata

type Output = ExtrinsicMetadata<PortableForm>

The portable version of Self.

fn into_portable(self, registry: &mut Registry) -> Self::Output

Convert self to the portable form by using the registry for caching.

impl<T: PartialEq + Form> PartialEq<ExtrinsicMetadata<T>> for ExtrinsicMetadata<T>where
    T::Type: PartialEq,

fn eq(&self, other: &ExtrinsicMetadata<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: Form> Serialize for ExtrinsicMetadata<T>where
    T::Type: Serialize,
    T::String: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T: Form> EncodeLike<ExtrinsicMetadata<T>> for ExtrinsicMetadata<T>where
    T::Type: Encode,
    Vec<SignedExtensionMetadata<T>>: Encode,

impl<T: Eq + Form> Eq for ExtrinsicMetadata<T>where
    T::Type: Eq,
