Modules

Macros

• declare_id
  Defines the program’s ID. This should be used at the root of all Anchor based programs.
• emit
  Logs an event that can be subscribed to by clients. Uses the sol_log_data syscall which results in the following log:
• err
  Returns with the given error. Use this with a custom error type.
• error
  Generates an Error::AnchorError that includes file and line information.
• msg
  Print a message to the log.
• require
  Ensures a condition is true, otherwise returns with the given error. Use this with or without a custom error type.
• require_eq
  Ensures two NON-PUBKEY values are equal.
• require_gt
  Ensures the first NON-PUBKEY value is greater than the second NON-PUBKEY value.
• require_gte
  Ensures the first NON-PUBKEY value is greater than or equal to the second NON-PUBKEY value.
• require_keys_eq
  Ensures two pubkeys values are equal.
• require_keys_neq
  Ensures two pubkeys are not equal.
• require_neq
  Ensures two NON-PUBKEY values are not equal.
• source
  Creates a Source

Structs

• Account
  Wrapper around AccountInfo that verifies program ownership and deserializes underlying data into a Rust type.
• AccountInfo
  Account information
• AccountLoader
  Type facilitating on demand zero copy deserialization.
• AccountMeta
  Describes a single account read or written by a program during instruction execution.
• AnchorError
• Clock
  A representation of network time.
• Context
  Provides non-argument inputs to the program.
• CpiContext
  Context specifying non-argument inputs for cross-program-invocations.
• EpochSchedule
• HplEvents
• Instructions
  Instructions sysvar, dummy type.
• Interface
  Type validating that the account is one of a set of given Programs
• InterfaceAccount
  Wrapper around AccountInfo that verifies program ownership and deserializes underlying data into a Rust type.
• Program
  Type validating that the account is the given Program
• ProgramData
• ProgramErrorWithOrigin
• Pubkey
  The address of a Solana account.
• Rent
  Configuration of network rent.
• Rewards
• Signer
  Type validating that the account signed the transaction. No other ownership or type checks are done. If this is used, one should not try to access the underlying account data.
• SlotHashes
• SlotHistory
  A bitvector indicating which slots are present in the past epoch.
• Source
• StakeHistory
• System
• SystemAccount
  Type validating that the account is owned by the system program
• Sysvar
  Type validating that the account is a sysvar and deserializing it.
• UncheckedAccount
  Explicit wrapper for AccountInfo types to emphasize that no checks are performed

Enums

• ComparedValues
• Error
• ErrorCode
  Error codes that can be returned by internal framework code.
• ErrorOrigin
• ProgramError
  Reasons the program may fail
• UpgradeableLoaderState
  Upgradeable loader account states

Constants

• ERROR_CODE_OFFSET
  The starting point for user defined error codes.

Statics

• ID
  The static program ID

Traits

• AccountDeserialize
  A data structure that can be deserialized and stored into account storage, i.e. an AccountInfo’s mutable data slice.
• AccountSerialize
  A data structure that can be serialized and stored into account storage, i.e. an AccountInfo’s mutable data slice.
• 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 derive macro to implement this trait.
• 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 structs.
• ToAccountMetas
  Transformation to AccountMeta structs.

Functions

• check_id
  Confirms that a given pubkey is equivalent to the program ID
• entrypoint^⚠
  Safety
• hpl_events
• id
  Returns the program ID
• next_account_info
  Convenience function for accessing the next item in an AccountInfo iterator.

Type Aliases

• Result

Attribute Macros

• 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 From on the ErrorCode to support converting from the user defined error enum into the generated Error.
• event
• program
  The #[program] attribute defines the module containing all instruction handlers defining all entries into a Solana program.
• zero_copy
  A data structure that can be used as an internal field for a zero copy deserialized account, i.e., a struct marked with #[account(zero_copy)].

Derive Macros

• Accounts
  Implements an Accounts deserializer on the given struct. Can provide further functionality through the use of attributes.
• AnchorDeserialize
• AnchorSerialize
• InitSpace
  Implements a Space trait on the given struct or enum.
