Trait Implementations

impl Clone for CodeMetadata

fn clone(&self) -> CodeMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CodeMetadata

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

Formats the value using the given formatter.

impl Decode for CodeMetadata

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 DecodeAsFields for CodeMetadata

fn decode_as_fields<'info, R: TypeResolver>( input: &mut &[u8], fields: &mut dyn FieldIter<'info, R::TypeId>, types: &'info R, ) -> Result<Self, Error>

Given some bytes and some fields denoting their structure, attempt to decode.

impl Encode for CodeMetadata

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 EncodeAsFields for CodeMetadata

fn encode_as_fields_to<ScaleEncodeResolver: TypeResolver>( &self, __encode_as_type_fields: &mut dyn FieldIter<'_, ScaleEncodeResolver::TypeId>, __encode_as_type_types: &ScaleEncodeResolver, __encode_as_type_out: &mut Vec<u8>, ) -> Result<(), Error>

Given some fields describing the shape of a type, attempt to encode to that shape.

fn encode_as_fields<R>( &self, fields: &mut dyn FieldIter<'_, <R as TypeResolver>::TypeId, Item = Field<'_, <R as TypeResolver>::TypeId>>, types: &R, ) -> Result<Vec<u8>, Error>

where R: TypeResolver,

This is a helper function which internally calls EncodeAsFields::encode_as_fields_to. Prefer to implement that instead.

impl EncodeAsType for CodeMetadata

fn encode_as_type_to<ScaleEncodeResolver: TypeResolver>( &self, __encode_as_type_type_id: ScaleEncodeResolver::TypeId, __encode_as_type_types: &ScaleEncodeResolver, __encode_as_type_out: &mut Vec<u8>, ) -> Result<(), Error>

Given some type_id, types, a context and some output target for the SCALE encoded bytes, attempt to SCALE encode the current value into the type given by type_id.

fn encode_as_type<R>( &self, type_id: <R as TypeResolver>::TypeId, types: &R, ) -> Result<Vec<u8>, Error>

where R: TypeResolver,

This is a helper function which internally calls EncodeAsType::encode_as_type_to. Prefer to implement that instead.

impl Hash for CodeMetadata

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, Self: Sized,

impl PartialEq for CodeMetadata

fn eq(&self, other: &CodeMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeInfo for CodeMetadata

type Identity = CodeMetadata

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
