Struct Message 

pub struct Message {
    pub header: MessageHeader,
    pub account_keys: Vec<Pubkey>,
    pub recent_blockhash: [u8; 32],
    pub instructions: Vec<CompiledInstruction>,
}

A Solana transaction message

Fields

header: MessageHeader

The message header, identifying signed and read-only account_keys.

account_keys: Vec<Pubkey>

List of account public keys

recent_blockhash: [u8; 32]

The blockhash of a recent block.

instructions: Vec<CompiledInstruction>

Instructions that will be executed in sequence and committed in one atomic transaction if all succeed.

Implementations

impl Message

pub fn new( header: MessageHeader, account_keys: Vec<Pubkey>, recent_blockhash: [u8; 32], instructions: Vec<CompiledInstruction>, ) -> Self

Create a new message

pub fn num_required_signatures(&self) -> u8

Get the number of required signatures

pub fn num_readonly_signed_accounts(&self) -> u8

Get the number of read-only signed accounts

pub fn num_readonly_unsigned_accounts(&self) -> u8

Get the number of read-only unsigned accounts

pub fn serialize_for_signing(&self) -> Result<Vec<u8>, String>

Serializes the message into the byte format required for signing and for the legacy transaction wire format.

Trait Implementations

impl BorshDeserialize for Message

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for Message

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for Message

fn clone(&self) -> Message

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Message

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Message

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
