Enum bdk_chain::bitcoin::blockdata::script::Instruction

pub enum Instruction<'a> {
    PushBytes(&'a PushBytes),
    Op(Opcode),
}
Expand description

A “parsed opcode” which allows iterating over a Script in a more sensible way.

Variants§

§

PushBytes(&'a PushBytes)

Push a bunch of data.

§

Op(Opcode)

Some non-push opcode.

Implementations§

§

impl<'a> Instruction<'a>

pub fn opcode(&self) -> Option<Opcode>

Returns the opcode if the instruction is not a data push.

pub fn push_bytes(&self) -> Option<&PushBytes>

Returns the pushed bytes if the instruction is a data push.

pub fn script_num(&self) -> Option<i64>

Returns the number interpretted by the script parser if it can be coerced into a number.

This does not require the script num to be minimal.
