Struct frame_metadata::v15::CustomMetadata

pub struct CustomMetadata<T: Form = MetaForm> {
    pub map: BTreeMap<T::String, CustomValueMetadata<T>>,
}

Metadata for custom types.

This map associates a string key to a CustomValueMetadata.

Fields

map: BTreeMap<T::String, CustomValueMetadata<T>>

The custom map.

Trait Implementations

impl<T: Clone + Form> Clone for CustomMetadata<T>

where T::String: Clone,

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

where T::String: Debug,

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

Formats the value using the given formatter.

impl<T: Form> Decode for CustomMetadata<T>

where BTreeMap<T::String, CustomValueMetadata<T>>: 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<T: Form> Encode for CustomMetadata<T>

where BTreeMap<T::String, CustomValueMetadata<T>>: 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<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

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 CustomMetadata

type Output = CustomMetadata<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 for CustomMetadata<T>

where T::String: PartialEq,

fn eq(&self, other: &CustomMetadata<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 CustomMetadata<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 for CustomMetadata<T>

where BTreeMap<T::String, CustomValueMetadata<T>>: Encode,

impl<T: Eq + Form> Eq for CustomMetadata<T>

where T::String: Eq,

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