Struct serde_scale_wrap::Wrap

pub struct Wrap<T>(pub T);

Wrapper for types serializable with serde to support serialization with Encode/Decode

This can help to pass instances of types implementing Serialize/Deserialize to substrate functions expecting types implementing Encode/Decode.

⚠ The Encode implementation panics if the serializer returns an error (e.g. when attempting to serialize a floating point number) because Encode methods do not return Result.

Trait Implementations

impl<T: Clone> Clone for Wrap<T>

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

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

Performs copy-assignment from source.

impl<T: Copy> Copy for Wrap<T>

impl<T: Debug> Debug for Wrap<T>

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

impl<'de, T: Deserialize<'de>> Decode for Wrap<T>

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

Attempt to deserialise the value from input.

impl<T: Default> Default for Wrap<T>

fn default() -> Wrap<T>

Returns the "default value" for a type.

impl<'de, T> Deserialize<'de> for Wrap<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: Serialize> Encode for Wrap<T>

fn encode_to<O: Output>(&self, dst: &mut O)

Panics

Panics if the serializer returns an error (e.g. when attempting to serialize a floating point number).

fn size_hint(&self) -> usize

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

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.

impl<T: Serialize> EncodeLike<Wrap<T>> for Wrap<T>

impl<T: Eq> Eq for Wrap<T>

impl<T: Hash> Hash for Wrap<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl<T: Ord> Ord for Wrap<T>

fn cmp(&self, other: &Wrap<T>) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl<T: PartialEq> PartialEq<Wrap<T>> for Wrap<T>

fn eq(&self, other: &Wrap<T>) -> bool

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Wrap<T>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Wrap<T>) -> bool

    T: Serialize, 

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