Enum ExtensionVariant 

pub enum ExtensionVariant<ExtensionV0, ExtensionOtherVersions> {
    V0(ExtensionV0),
    Other(ExtensionOtherVersions),
}

A versioned transaction extension pipeline defined with 2 variants: one for the version 0 and one for other versions.

The generic ExtensionOtherVersions should not re-define a transaction extension pipeline for the version 0, it will be ignored. The transaction extension pipeline for the version 0 is defined by the generic ExtensionV0.

Variants

V0(ExtensionV0)

A transaction extension pipeline for the version 0.

Other(ExtensionOtherVersions)

A transaction extension pipeline for other versions.

Trait Implementations

impl<ExtensionV0: Clone, ExtensionOtherVersions: Clone> Clone for ExtensionVariant<ExtensionV0, ExtensionOtherVersions>

fn clone(&self) -> ExtensionVariant<ExtensionV0, ExtensionOtherVersions>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<ExtensionV0: Debug, ExtensionOtherVersions: Debug> Debug for ExtensionVariant<ExtensionV0, ExtensionOtherVersions>

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

Formats the value using the given formatter.

impl<ExtensionV0: Decode, ExtensionOtherVersions: DecodeWithVersion> DecodeWithVersion for ExtensionVariant<ExtensionV0, ExtensionOtherVersions>

fn decode_with_version<I: Input>( extension_version: u8, input: &mut I, ) -> Result<Self, Error>

Decode the type from the given version and input.

impl<ExtensionV0: Encode, ExtensionOtherVersions: Encode> Encode for ExtensionVariant<ExtensionV0, ExtensionOtherVersions>

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn size_hint(&self) -> usize

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

fn encode_to<T: Output + ?Sized>(&self, dest: &mut T)

Convert self to a slice and append it to the destination.

fn encoded_size(&self) -> usize

Calculates the encoded size.

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.

impl<ExtensionV0: PartialEq, ExtensionOtherVersions: PartialEq> PartialEq for ExtensionVariant<ExtensionV0, ExtensionOtherVersions>

fn eq( &self, other: &ExtensionVariant<ExtensionV0, ExtensionOtherVersions>, ) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Dispatch a transaction.

fn weight(&self, call: &Call) -> Weight

Return the pre dispatch weight for the given versioned transaction extension pipeline and call.

impl<ExtensionV0, ExtensionOtherVersions: PipelineVersion> PipelineVersion for ExtensionVariant<ExtensionV0, ExtensionOtherVersions>

fn version(&self) -> u8

Return the version for the given versioned transaction extension pipeline.
