pub struct TransactionGroup { /* private fields */ }

Transaction Group.

Implementations

impl TransactionGroup

pub fn with_options_and_luts( options: TransactionGroupOptions, luts: AddressLookupTables, ) -> TransactionGroup

Create with the given TransactionGroupOptions and AddressLookupTables.

pub fn validate_instruction_group( &self, group: &ParallelGroup, ) -> Result<(), Error>

Returns Ok if the given ParallelGroup can be added without error.

pub fn add( &mut self, group: impl Into<ParallelGroup>, ) -> Result<&mut TransactionGroup, Error>

Add a ParallelGroup.

pub fn optimize(&mut self, allow_payer_change: bool) -> &mut TransactionGroup

Optimize the transactions by repacking instructions to maximize space efficiency.

pub fn to_transactions<'a, C>( &'a self, signers: &'a TransactionSigners<C>, recent_blockhash: Hash, allow_partial_sign: bool, ) -> TransactionGroupIter<'a, C, fn(&VersionedMessage) -> Result<(), Error>>

where C: Deref<Target = impl Signer + ?Sized>,

Build transactions.

pub fn to_transactions_with_options<'a, C, F>( &'a self, signers: &'a TransactionSigners<C>, recent_blockhash: Hash, allow_partial_sign: bool, compute_budget: ComputeBudgetOptions, before_sign: F, ) -> TransactionGroupIter<'a, C, F>

where C: Deref<Target = impl Signer + ?Sized>, F: FnMut(&VersionedMessage) -> Result<(), Error>,
