    // Required methods
    fn version(&self) -> i32;
    fn inputs(&self) -> &[Self::Input];
    fn outputs(&self) -> &[Self::Output];
    fn lock_time(&self) -> u32;

    // Provided methods
    fn input(&self, index: usize) -> Option<&Self::Input> { ... }
    fn output(&self, index: usize) -> Option<&Self::Output> { ... }
    fn input_count(&self) -> usize { ... }
    fn output_count(&self) -> usize { ... }
}

Full transaction context for script validation.

This trait provides all the data needed by the Spend validator to validate a transaction input. The Transaction module will implement this trait.
