Variants

Plain(T::Type)

Plain storage entry (just the value).

Map

Fields

hashers: Vec<StorageHasher>

One or more hashers, should be one hasher per key element.

key: T::Type

The type of the key, can be a tuple with elements for each of the hashers.

value: T::Type

The type of the value.

A storage map.

Trait Implementations

impl<T: Clone + Form> Clone for StorageEntryType<T>where
    T::Type: Clone,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Form> Debug for StorageEntryType<T>where
    T::Type: Debug,

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

Formats the value using the given formatter.

impl<T: Form> Decode for StorageEntryType<T>where
    T::Type: Decode,

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

Attempt to deserialise the value from input.

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<T: Form> Encode for StorageEntryType<T>where
    T::Type: Encode,

fn encode_to<__CodecOutputEdqy: Output + ?Sized>(
    &self,
    __codec_dest_edqy: &mut __CodecOutputEdqy
)

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

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

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 IntoPortable for StorageEntryType

type Output = StorageEntryType<PortableForm>

The portable version of Self.

fn into_portable(self, registry: &mut Registry) -> Self::Output

Convert self to the portable form by using the registry for caching.

impl<T: PartialEq + Form> PartialEq<StorageEntryType<T>> for StorageEntryType<T>where
    T::Type: PartialEq,

fn eq(&self, other: &StorageEntryType<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: Form> Serialize for StorageEntryType<T>where
    T::Type: Serialize,
    T::String: 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: Form> EncodeLike<StorageEntryType<T>> for StorageEntryType<T>where
    T::Type: Encode,

impl<T: Eq + Form> Eq for StorageEntryType<T>where
    T::Type: Eq,

impl<T: Form> StructuralEq for StorageEntryType<T>

impl<T: Form> StructuralPartialEq for StorageEntryType<T>
