Struct InvocationScript 

pub struct InvocationScript { /* private fields */ }

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

impl InvocationScript

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

This invocation script as a byte array

impl InvocationScript

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

This invocation script as a byte array

impl InvocationScript

pub fn new() -> Self

Constructs an empty invocation script.

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

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

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

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

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

Constructs an invocation script from the given signatures.

Arguments

• signatures - The signatures

Returns

The invocation script

pub fn try_encode(&self, writer: &mut Encoder) -> Result<(), BuilderError>

pub fn try_to_array(&self) -> Result<Vec<u8>, BuilderError>

impl InvocationScript

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

Trait Implementations

impl Clone for InvocationScript

fn clone(&self) -> InvocationScript

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InvocationScript

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for InvocationScript

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for InvocationScript

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for InvocationScript

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl NeoSerializable for InvocationScript

type Error = BuilderError

fn size(&self) -> usize

fn encode(&self, writer: &mut Encoder)

fn decode(reader: &mut Decoder<'_>) -> Result<Self, Self::Error>

fn to_array(&self) -> Vec<u8>

impl PartialEq for InvocationScript

fn eq(&self, other: &InvocationScript) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for InvocationScript

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for InvocationScript

impl StructuralPartialEq for InvocationScript
