Required Methods

fn num_total_signatures(&self) -> u64

Returns the total number of signatures in the message. This includes required transaction signatures as well as any pre-compile signatures that are attached in instructions.

fn num_write_locks(&self) -> u64

Returns the number of requested write-locks in this message. This does not consider if write-locks are demoted.

fn recent_blockhash(&self) -> &Hash

Return the recent blockhash.

fn num_instructions(&self) -> usize

Return the number of instructions in the message.

fn instructions_iter(&self) -> impl Iterator<Item = SVMInstruction<'_>>

Return an iterator over the instructions in the message.

fn program_instructions_iter( &self, ) -> impl Iterator<Item = (&Pubkey, SVMInstruction<'_>)>

Return an iterator over the instructions in the message, paired with the pubkey of the program.

fn account_keys(&self) -> AccountKeys<'_>

Return the account keys.

fn fee_payer(&self) -> &Pubkey

Return the fee-payer

fn is_writable(&self, index: usize) -> bool

Returns true if the account at index is writable.

fn is_signer(&self, index: usize) -> bool

Returns true if the account at index is signer.

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

Returns true if the account at the specified index is invoked as a program in top-level instructions of this message.

fn num_lookup_tables(&self) -> usize

Get the number of lookup tables.

fn message_address_table_lookups( &self, ) -> impl Iterator<Item = SVMMessageAddressTableLookup<'_>>

Get message address table lookups used in the message

Provided Methods

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

Returns true if the account at the specified index is an input to some program instruction in this message.

fn get_durable_nonce(&self) -> Option<&Pubkey>

If the message uses a durable nonce, return the pubkey of the nonce account

fn get_ix_signers(&self, index: usize) -> impl Iterator<Item = &Pubkey>

For the instruction at index, return an iterator over input accounts that are signers.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
