Struct sp_runtime::OpaqueExtrinsic

pub struct OpaqueExtrinsic(_);

Simple blob to hold an extrinsic without committing to its format and ensure it is serialized correctly.

Implementations

impl OpaqueExtrinsic

pub fn from_bytes(bytes: &[u8]) -> Result<Self, Error>

Convert an encoded extrinsic to an OpaqueExtrinsic.

Trait Implementations

impl Clone for OpaqueExtrinsic

fn clone(&self) -> OpaqueExtrinsic

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpaqueExtrinsic

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

Formats the value using the given formatter.

impl Decode for OpaqueExtrinsic

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, 

Attempt to skip the encoded value from input.

pub fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Default for OpaqueExtrinsic

fn default() -> OpaqueExtrinsic

Returns the “default value” for a type.

impl<'a> Deserialize<'a> for OpaqueExtrinsic

fn deserialize<D>(de: D) -> Result<Self, D::Error> where
    D: Deserializer<'a>, 

Deserialize this value from the given Serde deserializer.

impl Encode for OpaqueExtrinsic

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

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

pub fn encoded_size(&self) -> usize

Calculates the encoded size.

impl Extrinsic for OpaqueExtrinsic

type Call = ()

The function call.

type SignaturePayload = ()

The payload we carry for signed extrinsics.

fn is_signed(&self) -> Option<bool>

Is this Extrinsic signed? If no information are available about signed/unsigned, None should be returned.

fn new(
    _call: Self::Call,
    _signed_data: Option<Self::SignaturePayload>
) -> Option<Self>

Create new instance of the extrinsic.

impl<Address, Call, Signature, Extra> From<UncheckedExtrinsic<Address, Call, Signature, Extra>> for OpaqueExtrinsic where
    Address: Encode,
    Signature: Encode,
    Call: Encode,
    Extra: SignedExtension, 

fn from(extrinsic: UncheckedExtrinsic<Address, Call, Signature, Extra>) -> Self

Performs the conversion.

impl MallocSizeOf for OpaqueExtrinsic

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself. If T::size_of is a constant, consider implementing constant_size as well.

pub fn constant_size() -> Option<usize>

Used to optimize MallocSizeOf implementation for collections like Vec and HashMap to avoid iterating over them unnecessarily. The Self: Sized bound is for object safety.

impl PartialEq<OpaqueExtrinsic> for OpaqueExtrinsic

fn eq(&self, other: &OpaqueExtrinsic) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &OpaqueExtrinsic) -> bool

This method tests for !=.

impl Serialize for OpaqueExtrinsic

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

Serialize this value into the given Serde serializer.
