Struct frame_support::traits::WrapperOpaque

pub struct WrapperOpaque<T>(pub T);

A wrapper for any type T which implement encode/decode in a way compatible with Vec<u8>.

The encoding is the encoding of T prepended with the compact encoding of its size in bytes. Thus the encoded value can be decoded as a Vec<u8>.

Trait Implementations

impl<T: Clone> Clone for WrapperOpaque<T>

fn clone(&self) -> WrapperOpaque<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for WrapperOpaque<T>

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

Formats the value using the given formatter.

impl<T: Decode> Decode for WrapperOpaque<T>

fn decode<I: Input>(input: &mut I) -> Result<Self, Error>

Attempt to deserialise the value from input.

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

Attempt to skip the encoded 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 encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<T: Default> Default for WrapperOpaque<T>

fn default() -> WrapperOpaque<T>

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for WrapperOpaque<T>where
    T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Encode> Encode for WrapperOpaque<T>

fn size_hint(&self) -> usize

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

fn encode_to<O: Output + ?Sized>(&self, dest: &mut O)

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: FnOnce(&[u8]) -> R>(&self, f: F) -> R

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T> From<T> for WrapperOpaque<T>

fn from(t: T) -> Self

Converts to this type from the input type.

impl<T: MaxEncodedLen> MaxEncodedLen for WrapperOpaque<T>

fn max_encoded_len() -> usize

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

impl<T: PartialEq> PartialEq<WrapperOpaque<T>> for WrapperOpaque<T>

fn eq(&self, other: &WrapperOpaque<T>) -> 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<T> Serialize for WrapperOpaque<T>where
    T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T: TypeInfo + 'static> TypeInfo for WrapperOpaque<T>

type Identity = WrapperOpaque<T>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
