Trait Block

pub trait Block:

    // Required method
    fn execute(&mut self, runtime: &dyn BlockRuntime) -> BlockResult;

    // Provided method
    fn prepare(&mut self, _runtime: &dyn BlockRuntime) -> BlockResult { ... }
}

A block is an autonomous unit of computation in a system.

Required Methods

fn execute(&mut self, runtime: &dyn BlockRuntime) -> BlockResult

Executes this block’s computation.

Provided Methods

fn prepare(&mut self, _runtime: &dyn BlockRuntime) -> BlockResult

Prepares this block for execution.

This is called once before the first call to execute. This is where to open ports and allocate resources.
