Struct pallet_babe::CurrentBlockRandomness
source · pub struct CurrentBlockRandomness<T>(_);👎Deprecated: Should not be relied upon for correctness, will not provide fresh randomness for the current block. Please use
ParentBlockRandomness instead.Expand description
Randomness produced semi-freshly with each block, but inherits limitations of
RandomnessFromTwoEpochsAgo from which it derives.

Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read moresource§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

Convert
Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read moresource§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s. Read moresource§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s. Read moresource§impl<T> Instrument for T
