Struct Static

pub struct Static<T>(pub T);

If the type inside this implements Encode, this will implement scale_encode::EncodeAsType. If the type inside this implements Decode, this will implement scale_decode::DecodeAsType.

In either direction, we ignore any type information and just attempt to encode/decode statically via the Encode and Decode implementations. This can be useful as an adapter for types which do not implement scale_encode::EncodeAsType and scale_decode::DecodeAsType themselves, but it’s best to avoid using it where possible as it will not take into account any type information, and is thus more likely to encode or decode incorrectly.

Trait Implementations

impl<T: Clone> Clone for Static<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Static<T>

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

Formats the value using the given formatter.

impl<T> Decode for Static<T>

where 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> Deref for Static<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for Static<T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T> Encode for Static<T>

where 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<T: Encode> EncodeAsType for Static<T>

fn encode_as_type_to<R: TypeResolver>( &self, _type_id: R::TypeId, _types: &R, 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<T> From<T> for Static<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for Static<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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: Decode> IntoVisitor for Static<T>

type AnyVisitor<R: TypeResolver> = StaticDecodeAsTypeVisitor<T, R>

The visitor type used to decode SCALE encoded bytes to Self.

fn into_visitor<R: TypeResolver>() -> StaticDecodeAsTypeVisitor<T, R>

A means of obtaining this visitor.

impl<T: Ord> Ord for Static<T>

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

This method returns an Ordering between self and other.

fn eq(&self, other: &Static<T>) -> 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.

fn partial_cmp(&self, other: &Static<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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