Associated Types

Required methods

Returns the current block number.

Provides an abstraction over an arbitrary way of providing the current block number.

In case of using crate tp_runtime without the crate fabric system, it is already implemented for fabric_system::Module<T: Config> as:

ⓘ
fn current_block_number() -> Self {
    fabric_system::Module<Config>::block_number()
}
