pub trait ProvidesBlockchainMeta: Sync {
// Required method
fn latest_block_number(
&self,
) -> impl Send + Future<Output = Result<usize, InterfaceError>>;
}Expand description
Provides metadata from the blockchain.
Required Methods§
Sourcefn latest_block_number(
&self,
) -> impl Send + Future<Output = Result<usize, InterfaceError>>
fn latest_block_number( &self, ) -> impl Send + Future<Output = Result<usize, InterfaceError>>
Get the number of the latest block.
The number of a block is its index on the blockchain, so the genesis block would have
number = 0.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
