Struct MintExtensionFlags 

pub struct MintExtensionFlags {
    pub has_pausable: bool,
    pub has_permanent_delegate: bool,
    pub has_default_account_state: bool,
    pub default_state_frozen: bool,
    pub has_transfer_fee: bool,
    pub has_transfer_hook: bool,
}

Flags for mint extensions that affect Token account initialization and transfers

Fields

has_pausable: bool

Whether the mint has the PausableAccount extension

has_permanent_delegate: bool

Whether the mint has the PermanentDelegate extension

has_default_account_state: bool

Whether the mint has the DefaultAccountState extension (restricted regardless of state)

default_state_frozen: bool

Whether DefaultAccountState is currently set to Frozen (for Token account creation)

has_transfer_fee: bool

Whether the mint has the TransferFeeConfig extension

has_transfer_hook: bool

Whether the mint has the TransferHook extension (with nil program_id)

Implementations

impl MintExtensionFlags

pub fn num_token_account_extensions(&self) -> usize

pub fn calculate_account_size( &self, compressible: bool, ) -> Result<u64, ZeroCopyError>

Calculate the token account size based on extension flags.

Arguments

• compressible - If true, includes the Compressible extension in the size calculation

Returns

• Ok(u64) - The account size in bytes
• Err(ZeroCopyError) - If extension size calculation fails

pub const fn has_restricted_extensions(&self) -> bool

Returns true if mint has any restricted extensions. Restricted extensions (Pausable, PermanentDelegate, TransferFee, TransferHook, DefaultAccountState) require compression_only mode when compressing tokens.
