Expand description

A key value state at any storage level.

Fields

state_root: Vec<u8>

State root of the level, for top trie it is as an empty byte array.

parent_storage_keys: Vec<Vec<u8>>

Storage of parents, empty for top root or when exporting (building proof).

key_values: Vec<(Vec<u8>, Vec<u8>)>

Pair of key and values from this state.

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

source

pub 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 more

source

pub 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 more
