Struct BlockGenesisArgs

Source

pub struct BlockGenesisArgs<'external_args> { /* private fields */ }

Expand description

Data structure containing expected input for external method invocation, eventually calling block_genesis() on the other side by the host.

This can be used with Env, though there are helper methods on this provided by extension trait that allow not dealing with this struct directly in simpler cases.
