source

fn current_block_number() -> Self::BlockNumber

Returns the current block number.

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

In case of using crate sp_runtime with the crate frame-system, it is already implemented for frame_system::Pallet<T: Config> as:

ⓘ
fn current_block_number() -> Self {
    frame_system::Pallet<Config>::block_number()
}

.
