pub fn to_p2sh(&self) -> Script
[src]
Compute the P2SH output corresponding to this redeem script
pub fn to_v0_p2wsh(&self) -> Script
[src]
Compute the P2WSH output corresponding to this witnessScript (aka the "witness redeem script")
pub fn is_p2sh(&self) -> bool
[src]
Checks whether a script pubkey is a p2sh output
pub fn is_p2pkh(&self) -> bool

pub fn instructions(&self) -> Instructions<'_>ⓘNotable traits for Instructions<'a>
impl<'a> Iterator for Instructions<'a> type Item = Result<Instruction<'a>, Error>;
[src]
Notable traits for Instructions<'a>
impl<'a> Iterator for Instructions<'a> type Item = Result<Instruction<'a>, Error>;
Iterate over the script in the form of Instruction
s, 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<'_>ⓘNotable traits for Instructions<'a>
impl<'a> Iterator for Instructions<'a> type Item = Result<Instruction<'a>, Error>;
[src]
Notable traits for Instructions<'a>
impl<'a> Iterator for Instructions<'a> type Item = Result<Instruction<'a>, Error>;
Iterate over the script in the form of Instruction
s while enforcing
minimal pushes.
pub fn fmt_asm(&self, f: &mut dyn Write) -> Result
[src]
Write the assembly decoding of the script to the formatter.
pub fn asm(&self) -> String
[src]
Get the assembly decoding of the script.
