Struct solana_program::message::Message

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

Fields

header: MessageHeader

The message header, identifying signed and read-only account_keys NOTE: Serialization-related changes must be paired with the direct read at sigverify.

account_keys: Vec<Pubkey>

All the account keys used by this transaction

recent_blockhash: Hash

The id of a recent ledger entry.

instructions: Vec<CompiledInstruction>

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