Enum spl_token_2022::extension::ExtensionType

#[repr(u16)]
pub enum ExtensionType {
    Uninitialized,
    TransferFeeConfig,
    TransferFeeAmount,
    MintCloseAuthority,
    ConfidentialTransferMint,
    ConfidentialTransferAccount,
    DefaultAccountState,
    ImmutableOwner,
    MemoTransfer,
}

Extensions that can be applied to mints or accounts. Mint extensions must only be applied to mint accounts, and account extensions must only be applied to token holding accounts.

Variants

Uninitialized

Used as padding if the account size would otherwise be 355, same as a multisig

TransferFeeConfig

Includes transfer fee rate info and accompanying authorities to withdraw and set the fee

TransferFeeAmount

Includes withheld transfer fees

MintCloseAuthority

Includes an optional mint close authority

ConfidentialTransferMint

Auditor configuration for confidential transfers

ConfidentialTransferAccount

State for confidential transfers

DefaultAccountState

Specifies the default Account::state for new Accounts

ImmutableOwner

Indicates that the Account owner authority cannot be changed

MemoTransfer

Require inbound transfers to have memo

Implementations

impl ExtensionType

pub fn get_type_len(&self) -> usize

Get the data length of the type associated with the enum

pub fn get_account_len<S: BaseState>(extension_types: &[Self]) -> usize

Get the required account data length for the given ExtensionTypes

pub fn get_account_type(&self) -> AccountType

Get the associated account type

pub fn get_required_init_account_extensions(
    mint_extension_types: &[Self]
) -> Vec<Self>

Based on a set of AccountType::Mint ExtensionTypes, get the list of AccountType::Account ExtensionTypes required on InitializeAccount
