Enum frame_support::Void

pub enum Void {}

The void type - it cannot exist.

Trait Implementations

impl Clone for Void

pub fn clone(&self) -> Void

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Void

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

Formats the value using the given formatter.

impl Decode for Void

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

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 Encode for Void

pub fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

pub fn encode_to<T>(&self, dest: &mut T) where
    T: Output + ?Sized, 

Convert self to a slice and append it to the destination.

pub fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

pub 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.

pub fn encoded_size(&self) -> usize

Calculates the encoded size.

impl PartialEq<Void> for Void

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

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

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