Trait Implementations

impl<A: Action, Ta: Clone> Action for ActionWrapper<A, Ta>

type Target = Ta

Action target.

fn target(&self) -> Self::Target

Returns underlying action target.

fn len(&self) -> u32

Returns action unit length.

fn is_empty(&self) -> bool

Returns true if the action unit count is equal to zero.

fn modify<T, S, F, R, E>(self, f: F) -> Result<R, E>where F: FnOnce(Self, &mut S) -> Result<R, E>, <Self::Target as Associated<T>>::Value: TryInto<S>, S: Into<<Self::Target as Associated<T>>::Value>, E: From<ActionExecutionError> + From<NonceError>, Self::Target: StorageRef<T>,

Calls supplied function accepting an action along with a mutable reference to the value associated with the target.

fn view<T, S, F, R, E>(self, f: F) -> Result<R, E>where F: FnOnce(Self, S) -> Result<R, E>, <Self::Target as Associated<T>>::Value: TryInto<S>, S: Into<<Self::Target as Associated<T>>::Value>, E: From<ActionExecutionError> + From<NonceError>, Self::Target: StorageRef<T>,

Calls supplied function accepting an action along with a value associated with the target.

fn modify_removable<T, S, F, R, E>(self, f: F) -> Result<R, E>where F: FnOnce(Self, &mut Option<S>) -> Result<R, E>, <Self::Target as Associated<T>>::Value: TryInto<S>, S: Into<<Self::Target as Associated<T>>::Value>, E: From<ActionExecutionError> + From<NonceError>, Self::Target: StorageRef<T>,

Calls supplied function accepting an action along with a mutable reference to the option possibly containing a value associated with the target. Modifying supplied Option<_> to None will lead to the value removal.

fn multi_signed<T, S, SI>( self, signatures: SI ) -> MultiSignedAction<T, Self, S, SI::IntoIter>where T: Types, S: Signature, SI: IntoIterator, SI::IntoIter: FusedIterator<Item = SignatureWithNonce<T::BlockNumber, S>>,

Combines underlying action with the provided signatures.

impl<A: Clone, Ta: Clone> Clone for ActionWrapper<A, Ta>

fn clone(&self) -> ActionWrapper<A, Ta>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A: Debug, Ta: Debug> Debug for ActionWrapper<A, Ta>

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

Formats the value using the given formatter.

impl<A, Ta> Decode for ActionWrapper<A, Ta>where Ta: Decode, A: Decode,

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<A, Ta> Encode for ActionWrapper<A, Ta>where Ta: Encode, A: Encode,

fn size_hint(&self) -> usize

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

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, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<A: PartialEq, Ta: PartialEq> PartialEq<ActionWrapper<A, Ta>> for ActionWrapper<A, Ta>

fn eq(&self, other: &ActionWrapper<A, Ta>) -> bool

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

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

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

fn to_state_change(&self) -> StateChange<'_, T>

Converts the given entity to the state change.

type Identity = ActionWrapper<A, Ta>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
