Fields

num_required_signatures: u8

Number of required signatures.

num_readonly_signed_accounts: u8

Number of read-only signed accounts.

num_readonly_unsigned_accounts: u8

Number of read-only unsigned accounts.

account_keys: Vec<[u8; 32]>

All account keys referenced by the message.

recent_blockhash: [u8; 32]

Recent blockhash (32 bytes).

instructions: Vec<CompiledInstruction>

Compiled instructions.

Implementations

impl Message

pub fn new(instructions: &[Instruction], fee_payer: [u8; 32]) -> Self

Build a message from instructions and a fee payer.

Panics

Panics if any instruction references an account key not present in the deduplicated key list, or if the key list exceeds 256 entries. Use try_new for the fallible version.

pub fn try_new( instructions: &[Instruction], fee_payer: [u8; 32], ) -> Result<Self, SignerError>

Fallible version of new.

Returns an error if any instruction references an account key not present in the deduplicated key list, or if the key list exceeds 256.

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

Serialize the message to bytes for signing.

impl Message

pub fn deserialize(data: &[u8]) -> Result<Self, SignerError>

Deserialize a legacy message from wire-format bytes.

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.
