Struct PackedAccounts 

pub struct PackedAccounts(pub PackedAccounts<AccountMeta>);

Packs accounts and creates indices for instruction building (client-side).

Wraps the generic PackedAccounts<AccountMeta> from sdk-types with Solana-specific system account helpers as inherent methods.

Implementations

impl PackedAccounts

pub fn new_with_system_accounts(config: SystemAccountMetaConfig) -> Result<Self>

Creates a new PackedAccounts with v1 system accounts pre-configured.

Use with cpi::v1::CpiAccounts on the program side.

pub fn add_system_accounts( &mut self, config: SystemAccountMetaConfig, ) -> Result<()>

Adds v1 Light system program accounts to the account list.

Use with cpi::v1::CpiAccounts on the program side.

This adds all the accounts required by the Light system program for v1 operations, including the CPI authority, registered programs, account compression program, and Noop program.

pub fn add_system_accounts_v2( &mut self, config: SystemAccountMetaConfig, ) -> Result<()>

Adds v2 Light system program accounts to the account list.

Use with cpi::v2::CpiAccounts on the program side.

This adds all the accounts required by the Light system program for v2 operations. V2 uses a different account layout optimized for batched state trees.

pub fn system_accounts_set(&self) -> bool

pub fn add_pre_accounts_signer( &mut self, pubkey: <AM as AccountMetaTrait>::Pubkey, )

pub fn add_pre_accounts_signer_mut( &mut self, pubkey: <AM as AccountMetaTrait>::Pubkey, )

pub fn add_pre_accounts_meta(&mut self, account_meta: AM)

pub fn add_pre_accounts_metas(&mut self, account_metas: &[AM])

pub fn add_system_accounts_raw(&mut self, system_accounts: Vec<AM>)

pub fn insert_or_get(&mut self, pubkey: <AM as AccountMetaTrait>::Pubkey) -> u8

Returns the index of the provided pubkey in the collection.

If the provided pubkey is not a part of the collection, it gets inserted with a next_index.

If the provided pubkey already exists in the collection, its already existing index is returned.

pub fn insert_or_get_read_only( &mut self, pubkey: <AM as AccountMetaTrait>::Pubkey, ) -> u8

pub fn insert_or_get_config( &mut self, pubkey: <AM as AccountMetaTrait>::Pubkey, is_signer: bool, is_writable: bool, ) -> u8

pub fn to_account_metas(&self) -> (Vec<AM>, usize, usize)

Converts the collection of accounts to a vector of account metas, which can be used as remaining accounts in instructions or CPI calls.

Returns

A tuple of (account_metas, system_accounts_offset, packed_accounts_offset):

• account_metas: All accounts concatenated in order: [pre_accounts][system_accounts][packed_accounts]
• system_accounts_offset: Index where system accounts start (= pre_accounts.len())
• packed_accounts_offset: Index where packed accounts start (= pre_accounts.len() + system_accounts.len())

pub fn packed_pubkeys(&self) -> Vec<[u8; 32]>

pub fn add_custom_system_accounts<T>( &mut self, accounts: T, ) -> Result<(), LightSdkTypesError>

where T: AccountMetasVec<AM>,
