Trait sp_runtime::traits::Applyable

pub trait Applyable: Sized + Send + Sync {
    type Call: Dispatchable;
    fn validate<V: ValidateUnsigned<Call = Self::Call>>(
        &self, 
        source: TransactionSource, 
        info: &DispatchInfoOf<Self::Call>, 
        len: usize
    ) -> TransactionValidity;
    fn apply<V: ValidateUnsigned<Call = Self::Call>>(
        self, 
        info: &DispatchInfoOf<Self::Call>, 
        len: usize
    ) -> ApplyExtrinsicResultWithInfo<PostDispatchInfoOf<Self::Call>>;
}

An “executable” piece of information, used by the standard Substrate Executive in order to enact a piece of extrinsic information by marshalling and dispatching to a named function call.

Also provides information on to whom this information is attributable and an index that allows each piece of attributable information to be disambiguated.

Associated Types

type Call: Dispatchable

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

Required methods

fn validate<V: 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<V: 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.
