Struct sp_io::Crossing

pub struct Crossing<T: Encode + Decode>(/* private fields */);

Crossing is a helper wrapping any Encode-Decodeable type for transferring over the wasm barrier.

Implementations

impl<T: Encode + Decode> Crossing<T>

pub fn into_inner(self) -> T

Convert into the inner type

Trait Implementations

impl<T> Decode for Crossing<T>

where T: Decode + Encode + 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 Crossing<T>

where T: Default + Encode + Decode,

fn default() -> Self

Returns the “default value” for a type.

impl<T> Encode for Crossing<T>

where T: Encode + Encode + Decode,

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 + Decode> PassBy for Crossing<T>

type PassBy = Codec<Crossing<T>>

The strategy that should be used to pass the type.

impl<T> EncodeLike for Crossing<T>

where T: Encode + Encode + Decode,
