pub fn dust_value(&self) -> Amount

Gets the minimum value an output with this script should have in order to be broadcastable on today’s bitcoin network.

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 Self::instructions_minimal.

Write the assembly decoding of the script to the formatter.

pub fn bytes_to_asm(script: &[u8]) -> String
