Implementations

impl<T, A, S, SI> MultiSignedAction<T, A, S, SI>where T: Types, A: Action, S: Signature, SI: FusedIterator<Item = SignatureWithNonce<<T as Types>::BlockNumber, S>>,

pub fn new<ISI>(action: A, signatures: ISI) -> MultiSignedAction<T, A, S, SI>where ISI: IntoIterator<IntoIter = SI>,

impl<T, A, S, SI> MultiSignedAction<T, A, S, SI>where T: Config, A: Action, <A as Action>::Target: StorageRef<T>, WithNonce<T, A>: ActionWithNonce<T> + ToStateChange<T>, <WithNonce<T, A> as Action>::Target: StorageRef<T>, S: Signature + AuthorizeSignedAction<T, WithNonce<T, A>>, <S as Signature>::Signer: AuthorizeTarget<T, <WithNonce<T, A> as Action>::Target, <S as Signature>::Key> + Ord + Deref, <<S as Signature>::Signer as Deref>::Target: AuthorizeTarget<T, <WithNonce<T, A> as Action>::Target, <S as Signature>::Key>, SI: FusedIterator<Item = SignatureWithNonce<<T as Config>::BlockNumber, S>>,

pub fn execute<F, R, E, V, RS>( self, f: F, get_required_signers: RS ) -> Result<R, IntermediateError<T>>where F: FnOnce(A, &mut <<A as Action>::Target as Associated<T>>::Value, BTreeSet<<S as Signature>::Signer, Global>) -> Result<R, E>, RS: FnOnce(&<<A as Action>::Target as Associated<T>>::Value) -> Option<InclusionRule<<S as Signature>::Signer>>, E: Into<IntermediateError<T>>, <<S as Signature>::Signer as Deref>::Target: StorageRef<T, Value = WithNonce<T, V>> + Clone,

Verifies signature and nonce for all required signers, then executes given action providing a mutable reference to the value associated with the target along with the set of actors that provided signatures. In case of a successful result, commits all storage changes and increases nonces for all signers.

pub fn execute_view<F, R, E, V, RS>( self, f: F, get_required_signers: RS ) -> Result<R, IntermediateError<T>>where F: FnOnce(A, <<A as Action>::Target as Associated<T>>::Value, BTreeSet<<S as Signature>::Signer, Global>) -> Result<R, E>, RS: FnOnce(&<<A as Action>::Target as Associated<T>>::Value) -> Option<InclusionRule<<S as Signature>::Signer>>, E: Into<IntermediateError<T>>, <<S as Signature>::Signer as Deref>::Target: StorageRef<T, Value = WithNonce<T, V>> + Clone,

Verifies signature and nonce for all required signers, then executes given action providing a value associated with the target along with the set of actors that provided signatures. In case of a successful result, commits all storage changes and increases nonces for all signers

pub fn execute_removable<F, R, E, V, RS>( self, f: F, get_required_signers: RS ) -> Result<R, IntermediateError<T>>where F: FnOnce(A, &mut Option<<<A as Action>::Target as Associated<T>>::Value>, BTreeSet<<S as Signature>::Signer, Global>) -> Result<R, E>, RS: FnOnce(Option<&<<A as Action>::Target as Associated<T>>::Value>) -> Option<InclusionRule<<S as Signature>::Signer>>, E: Into<IntermediateError<T>>, <<S as Signature>::Signer as Deref>::Target: StorageRef<T, Value = WithNonce<T, V>> + Clone,

Verifies signature and nonce for all required signers, then executes given action providing a mutable reference to the option containing value associated with the target along with the set of actors that provided signatures. In case of a successful result, commits all storage changes and increases nonces for all signers.
