Struct solana_sdk::message::Message

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

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, Global>

All the account keys used by this transaction

recent_blockhash: Hash

The id of a recent ledger entry.

instructions: Vec<CompiledInstruction, Global>

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

Trait Implementations

impl AbiExample for Message

pub fn example() -> Message

impl Clone for Message

pub 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

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

Formats the value using the given formatter.

impl Default for Message

pub fn default() -> Message

Returns the “default value” for a type.

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

pub 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 FromWasmAbi for Message

type Abi = u32

The wasm ABI type that this converts from when coming back out from the ABI boundary.

pub unsafe fn from_abi(js: u32) -> Message

Recover a Self from Self::Abi.

impl IntoWasmAbi for Message

type Abi = u32

The wasm ABI type that this converts into when crossing the ABI boundary.

pub fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl OptionFromWasmAbi for Message

pub fn is_none(abi: &<Message as FromWasmAbi>::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for Message

pub fn none() -> <Message as IntoWasmAbi>::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl PartialEq<Message> for Message

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

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

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

This method tests for !=.

impl RefFromWasmAbi for Message

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, Message>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

pub unsafe fn ref_from_abi(
    js: <Message as RefFromWasmAbi>::Abi
) -> <Message as RefFromWasmAbi>::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for Message

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, Message>

Same as RefFromWasmAbi::Anchor

pub unsafe fn ref_mut_from_abi(
    js: <Message as RefMutFromWasmAbi>::Abi
) -> <Message as RefMutFromWasmAbi>::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl Sanitize for Message

pub fn sanitize(&self) -> Result<(), SanitizeError>

impl Serialize for Message

pub fn serialize<__S>(
    &self,
    __serializer: __S

impl TryFrom<Message> for SanitizedMessage

type Error = SanitizeMessageError

The type returned in the event of a conversion error.

pub fn try_from(
    message: Message
) -> Result<SanitizedMessage, <SanitizedMessage as TryFrom<Message>>::Error>
