AccountDeserialize A data structure that can be deserialized and stored into account storage,
i.e. an
AccountInfo AccountSerialize A data structure that can be serialized and stored into account storage,
i.e. an
AccountInfo Accounts A data structure of validated accounts that can be deserialized from the
input to a Solana program. Implementations of this trait should perform any
and all requisite constraint checks on accounts to ensure the accounts
maintain any invariants required for the program to run securely. In most
cases, it’s recommended to use the Accounts AccountsClose The close procedure to initiate garabage collection of an account, allowing
one to retrieve the rent exemption. AccountsExit The exit procedure for an account. Any cleanup or persistence to storage
should be done here. AnchorDeserialize A data-structure that can be de-serialized from binary format by NBOR. AnchorSerialize A data-structure that can be serialized into binary format by NBOR. Id Defines the id of a program. Key Defines the Pubkey of an account. Lamports Lamports related utility methods for accounts. Owner Defines an address expected to own an account. SolanaSysvar A type that holds sysvar data. Space Defines the space of an account for initialization. ToAccountInfo Transformation to an AccountInfo struct. ToAccountInfos Transformation to
AccountInfo ToAccountMetas Transformation to
AccountMeta next_account_info Convenience function for accessing the next item in an AccountInfo Result access_control Executes the given access control method before running the decorated
instruction handler. Any method in scope of the attribute can be invoked
with any arguments from the associated instruction handler. account An attribute for a data structure representing a Solana account. constant A marker attribute used to mark const values that should be included in the
generated IDL but functionally does nothing. error_code Generates Error and type Result<T> = Result<T, Error> types to be
used as return types from Anchor instruction handlers. Importantly, the
attribute implements
FromErrorCode to support converting from the user defined error enum into
the generated Error. event The event attribute allows a struct to be used with
emit! so that programs can log significant events in
their programs that clients can subscribe to. Currently, this macro is for
structs only. program The #[program] attribute defines the module containing all instruction
handlers defining all entries into a Solana program. wasm_bindgen A list of all the attributes can be found here: https://rustwasm.github.io/docs/wasm-bindgen/reference/attributes/index.html zero_copy A data structure that can be used as an internal field for a zero copy
