A tag to indicate that both the C++ and Rust implementations of zcash_script should be used, with their results compared.

Trait Implementations

impl<T: ZcashScript, U: ZcashScript> ZcashScript for ComparisonInterpreter<T, U>

This implementation is functionally equivalent to the T impl, but it also runs a second (U) impl and logs a warning if they disagree.

fn legacy_sigop_count_script(&self, script: &[u8]) -> Result<u32, Error>

Returns the number of transparent signature operations in the input or output script pointed to by script.

fn verify_callback( &self, script_pub_key: &[u8], script_sig: &[u8], flags: VerificationFlags, ) -> Result<(), Error>

Returns Ok(()) if the a transparent input correctly spends the matching output under the additional constraints specified by flags. This function receives only the required information to validate the spend and not the transaction itself. In particular, the sighash for the spend is obtained using a callback function.
