Struct EnvironmentType 

pub struct EnvironmentType<T>(/* private fields */);

Wrapper around PhantomData to prevent it being filtered by scale-info.

scale-info filters out PhantomData fields because usually we are only interested in sized types. However, when trying to communicate types as opposed to values we want to have those zero sized types be included.

Trait Implementations

impl<T> Decode for EnvironmentType<T>

where PhantomData<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> Default for EnvironmentType<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for EnvironmentType<T>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> Encode for EnvironmentType<T>

where PhantomData<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> EncodeLike for EnvironmentType<T>

where PhantomData<T>: Encode,

impl<T> Serialize for EnvironmentType<T>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> TypeInfo for EnvironmentType<T>

where PhantomData<T>: TypeInfo + 'static, T: TypeInfo + 'static,

type Identity = EnvironmentType<T>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
