Struct sp_io::Crossing

pub struct Crossing<T: Encode + Decode>(_);

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: Encode + Decode> Decode for Crossing<T> where
    T: Decode,
    T: Decode, 

fn decode<__CodecInputEdqy: Input>(
    __codec_input_edqy: &mut __CodecInputEdqy
) -> Result<Self, Error>

Attempt to deserialise the value from input.

pub fn skip<I>(input: &mut I) -> Result<(), Error> where
    I: Input, 

Attempt to skip the encoded value from input.

pub fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<T> Default for Crossing<T> where
