Struct 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.

Trait Implementations

impl AbiExample for Message

fn example() -> Self

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 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 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 Sanitize for Message

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

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 TryFrom<Message> for SanitizedMessage

type Error = SanitizeMessageError

The type returned in the event of a conversion error.

fn try_from(message: Message) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Message

impl StructuralPartialEq for Message
