Trait Implementations

impl<DataSize: Clone + Get<u32> + Clone + Debug + PartialEq> Clone for ItemAction<DataSize>

fn clone(&self) -> ItemAction<DataSize>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<DataSize: Debug + Get<u32> + Clone + Debug + PartialEq> Debug for ItemAction<DataSize>

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

Formats the value using the given formatter.

impl<DataSize: Get<u32> + Clone + Debug + PartialEq> Decode for ItemAction<DataSize>

where BoundedVec<u8, DataSize>: 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<DataSize: Get<u32> + Clone + Debug + PartialEq> Encode for ItemAction<DataSize>

where BoundedVec<u8, DataSize>: 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>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where 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<DataSize> MaxEncodedLen for ItemAction<DataSize>

where DataSize: MaxEncodedLen + Get<u32> + Clone + Debug + PartialEq,

fn max_encoded_len() -> usize

Upper bound, in bytes, of the maximum encoded size of this item.

impl<DataSize: PartialEq + Get<u32> + Clone + Debug + PartialEq> PartialEq for ItemAction<DataSize>

fn eq(&self, other: &ItemAction<DataSize>) -> 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.

impl<DataSize> TypeInfo for ItemAction<DataSize>

where BoundedVec<u8, DataSize>: TypeInfo + 'static, DataSize: Get<u32> + Clone + Debug + PartialEq + 'static,

type Identity = ItemAction<DataSize>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl<DataSize: Get<u32> + Clone + Debug + PartialEq> EncodeLike for ItemAction<DataSize>

where BoundedVec<u8, DataSize>: Encode,

impl<DataSize: Get<u32> + Clone + Debug + PartialEq> StructuralPartialEq for ItemAction<DataSize>
