sourcepub fn verify_for_pending_block(
&self,
tx: &SignedTransaction,
header: &Header
) -> Result<(), Error>
pub fn verify_for_pending_block(
&self,
tx: &SignedTransaction,
header: &Header
) -> Result<(), Error>
Verifies transaction against its block (before its import into this block) Also Verifies if signed transaction is executable.
This should perform any verifications that rely on chain status.
