Struct CheckedExtrinsic 

pub struct CheckedExtrinsic<AccountId, Call, ExtensionV0, ExtensionOtherVersions = InvalidVersion> {
    pub format: ExtrinsicFormat<AccountId, ExtensionV0, ExtensionOtherVersions>,
    pub function: Call,
}

Definition of something that the external world might want to say; its existence implies that it has been checked and is good, particularly with regards to the signature.

This is typically passed into traits::Applyable::apply, which should execute CheckedExtrinsic::function, alongside all other bits and bobs.

Bare extrinsics and signed extrinsics are extended with the transaction extension version 0, specified by the generic parameter ExtensionV0.

General extrinsics support multiple transaction extension versions, specified by both ExtensionV0 and ExtensionOtherVersions, by default ExtensionOtherVersions is set to invalid version, making ExtensionV0 the only supported version. If you want to support more versions, you need to specify the ExtensionOtherVersions parameter.

Fields

format: ExtrinsicFormat<AccountId, ExtensionV0, ExtensionOtherVersions>

Who this purports to be from and the number of extrinsics have come before from the same signer, if anyone (note this is not a signature).

function: Call

The function that should be called.

Implementations

impl<AccountId, Call, ExtensionV0, ExtensionOtherVersions> CheckedExtrinsic<AccountId, Call, ExtensionV0, ExtensionOtherVersions>

where Call: Dispatchable + Encode, ExtensionV0: TransactionExtension<Call>, ExtensionOtherVersions: Pipeline<Call>, <Call as Dispatchable>::RuntimeOrigin: AsTransactionAuthorizedOrigin,

pub fn extension_weight(&self) -> Weight

Returns the weight of the extension of this transaction, if present. If the transaction doesn’t use any extension, the weight returned is equal to zero.

Trait Implementations

impl<AccountId, Call, ExtensionV0, ExtensionOtherVersions, RuntimeOrigin> Applyable for CheckedExtrinsic<AccountId, Call, ExtensionV0, ExtensionOtherVersions>

where AccountId: Member + MaybeDisplay, Call: Member + Dispatchable<RuntimeOrigin = RuntimeOrigin> + Encode, ExtensionV0: TransactionExtension<Call>, ExtensionOtherVersions: Pipeline<Call>, RuntimeOrigin: From<Option<AccountId>> + AsTransactionAuthorizedOrigin,

type Call = Call

Type by which we can dispatch. Restricts the UnsignedValidator type.

fn validate<I: ValidateUnsigned<Call = Self::Call>>( &self, source: TransactionSource, info: &DispatchInfoOf<Self::Call>, len: usize, ) -> TransactionValidity

Checks to see if this is a valid transaction. It returns information on it if so.

fn apply<I: ValidateUnsigned<Call = Self::Call>>( self, info: &DispatchInfoOf<Self::Call>, len: usize, ) -> ApplyExtrinsicResultWithInfo<PostDispatchInfoOf<Self::Call>>

Executes all necessary logic needed prior to dispatch and deconstructs into function call, index and sender.

impl<AccountId: Clone, Call: Clone, ExtensionV0: Clone, ExtensionOtherVersions: Clone> Clone for CheckedExtrinsic<AccountId, Call, ExtensionV0, ExtensionOtherVersions>

fn clone( &self, ) -> CheckedExtrinsic<AccountId, Call, ExtensionV0, ExtensionOtherVersions>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<AccountId: Debug, Call: Debug, ExtensionV0: Debug, ExtensionOtherVersions: Debug> Debug for CheckedExtrinsic<AccountId, Call, ExtensionV0, ExtensionOtherVersions>

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

Formats the value using the given formatter.

impl<AccountId: PartialEq, Call: PartialEq, ExtensionV0: PartialEq, ExtensionOtherVersions: PartialEq> PartialEq for CheckedExtrinsic<AccountId, Call, ExtensionV0, ExtensionOtherVersions>

fn eq( &self, other: &CheckedExtrinsic<AccountId, Call, 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.
