Checks whether a script pubkey is a p2pk output

pub fn is_witness_program(&self) -> bool

Checks whether a script pubkey is a Segregated Witness (segwit) program.

pub fn is_provably_unspendable(&self) -> bool

Whether a script can be proven to have no satisfying input In elements, is_provably_unspendable is consensus critical matches the implementation of CScript::IsUnspendable()

pub fn instructions(&self) -> Instructions<'_>

Iterate over the script in the form of Instructions, which are an enum covering opcodes, datapushes and errors. At most one error will be returned and then the iterator will end. To instead iterate over the script as sequence of bytes, treat it as a slice using script[..] or convert it to a vector using into_bytes().

To force minimal pushes, use [instructions_minimal].

pub fn instructions_minimal(&self) -> Instructions<'_>

Iterate over the script in the form of Instructions while enforcing minimal pushes.

pub fn fmt_asm(&self, f: &mut dyn Write) -> Result

Write the assembly decoding of the script to the formatter.

pub fn asm(&self) -> String

Get the assembly decoding of the script.
