Struct Message 

pub struct Message {
    pub header: MessageHeader,
    pub account_keys: Vec<Pubkey>,
    pub recent_blockhash: Hash,
    pub instructions: Vec<CompiledInstruction>,
    pub address_table_lookups: Vec<MessageAddressTableLookup>,
}

Fields

header: MessageHeader

The message header, identifying signed and read-only account_keys. Header values only describe static account_keys, they do not describe any additional account keys loaded via address table lookups.

account_keys: Vec<Pubkey>

List of accounts loaded by this transaction.

recent_blockhash: Hash

The blockhash of a recent block.

instructions: Vec<CompiledInstruction>

Instructions that invoke a designated program, are executed in sequence, and committed in one atomic transaction if all succeed.

Notes

Program indexes must index into the list of message account_keys because program id’s cannot be dynamically loaded from a lookup table.

Account indexes must index into the list of addresses constructed from the concatenation of three key lists:

1. message account_keys
2. ordered list of keys loaded from writable lookup table indexes
3. ordered list of keys loaded from readable lookup table indexes

address_table_lookups: Vec<MessageAddressTableLookup>

List of address table lookups used to load additional accounts for this transaction.

Trait Implementations

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 DecodableWithMeta for Message

type Encoded = UiMessage

type Decoded = Message

fn decode_with_meta( encoded: Self::Encoded, decoding: UiTransactionEncoding, version: Option<TransactionVersion>, ) -> Result<Self::Decoded, DecodeError>

fn json_decode( encoded: Self::Encoded, _version: Option<TransactionVersion>, ) -> Result<Self::Decoded, DecodeError>

impl Default for Message

fn default() -> Message

Returns the “default value” for a type.

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 From<Message> for Message

fn from(msg: Message) -> Self

Converts to this type from the input type.

impl PartialEq for Message

fn eq(&self, other: &Message) -> 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 Message

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 Message

impl StructuralPartialEq for Message
