Enum frame_support::Void [−][src]
pub enum Void {}
Expand description
The void type - it cannot exist.
Trait Implementations
Attempt to deserialise the value from input.
Attempt to skip the encoded value from input. Read more
fn encoded_fixed_size() -> Option<usize>
fn encoded_fixed_size() -> Option<usize>
Returns the fixed encoded size of the type. Read more
Convert self to a slice and append it to the destination.
Convert self to an owned vector.
fn using_encoded<R, F>(&self, f: F) -> R where
F: FnOnce(&[u8]) -> R,
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 into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>
pub fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

(where Trait: Downcast
) to Rc<Any>
. Rc<Any>
can then be
further downcast
into Rc<ConcreteType>
where ConcreteType
implements Trait

Convert &Trait
(where Trait: Downcast
) to &Any
. This is needed since Rust cannot
generate &Any
