Struct solana_sdk::message::v0::Message

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

A Solana transaction message (v0).

This message format supports succinct account loading with on-chain address lookup tables.

See the message module documentation for further description.

Fields

header: MessageHeader

The message header, identifying signed and read-only account_keys

account_keys: Vec<Pubkey, Global>

List of accounts loaded by this transaction.

recent_blockhash: Hash

The blockhash of a recent block.

instructions: Vec<CompiledInstruction, Global>

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

Notes

Account and program indexes will 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, Global>

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

Implementations

impl Message

pub fn serialize(&self) -> Vec<u8, Global>

Serialize this message with a version #0 prefix using bincode encoding.

pub fn is_key_called_as_program(&self, key_index: usize) -> bool

Returns true if the account at the specified index is called as a program by an instruction

pub fn is_maybe_writable(&self, key_index: usize) -> bool

Returns true if the account at the specified index was requested as writable. Before loading addresses, we can’t demote write locks for dynamically loaded addresses so this should not be used by the runtime.

Trait Implementations

impl AbiExample for Message

fn example() -> Message

impl Clone for Message

fn clone(&self) -> Message

Returns a copy 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<(), Error>

Formats the value using the given formatter.

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<Message, <__D as Deserializer<'de>>::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl PartialEq<Message> for Message

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
