Struct InvocationScript

Source
pub struct InvocationScript { /* private fields */ }
Expand description

An invocation script is part of a witness and is simply a sequence of neo-vm instructions.

The invocation script usually is the input to the verification script.

In most cases it will contain a signature that is checked in the verification script.

Implementations§

Source§

impl InvocationScript

Source

pub fn script(&self) -> &Vec<u8>

This invocation script as a byte array

Source§

impl InvocationScript

Source

pub fn set_script(&mut self, val: Vec<u8>) -> &mut Self

Source§

impl InvocationScript

Source

pub fn new() -> Self

Constructs an empty invocation script.

Source

pub fn new_with_script(script: Vec<u8>) -> Self

Creates an invocation script with the given script.

It is recommended to use InvocationScript::from_signature or InvocationScript::from_message_and_key_pair when you need a signature invocation script.

§Arguments
  • script - The script as a byte array
Source

pub fn from_serialized_script(script: Vec<u8>) -> Self

Source

pub fn from_signature(signature: Secp256r1Signature) -> Self

Creates an invocation script from the given signature.

§Arguments
  • signature - The signature to use in the script
§Returns

The constructed invocation script

Source

pub fn from_message_and_key_pair( message: Vec<u8>, key_pair: &KeyPair, ) -> Result<Self, BuilderError>

Creates an invocation script from the signature of the given message signed with the given key pair.

§Arguments
  • message - The message to sign
  • key_pair - The key to use for signing
§Returns

The constructed invocation script

Source

pub fn from_signatures(signatures: &[Secp256r1Signature]) -> Self

Constructs an invocation script from the given signatures.

§Arguments
  • signatures - The signatures
§Returns

The invocation script

Source§

impl InvocationScript

Source

pub fn get_signatures(&self) -> Vec<Secp256r1Signature>

Unbundles the script into a list of signatures if this invocation script contains signatures.

§Returns

The list of signatures found in this script
