Struct TransferHookAccountExtension 

#[repr(C)]
pub struct TransferHookAccountExtension {
    pub transferring: u8,
}

Extension indicating the account belongs to a mint with transfer hook. Contains a transferring flag used as a reentrancy guard during hook CPI. Consistent with SPL Token-2022 TransferHookAccount layout.

Fields

transferring: u8

Flag to indicate that the account is in the middle of a transfer. Used as reentrancy guard when transfer hook program is called via CPI. Always false at rest since we only support nil program_id (no hook invoked).

Trait Implementations

impl BorshDeserialize for TransferHookAccountExtension

where u8: BorshDeserialize,

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for TransferHookAccountExtension

where u8: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for TransferHookAccountExtension

fn clone(&self) -> TransferHookAccountExtension

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransferHookAccountExtension

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TransferHookAccountExtension

fn default() -> TransferHookAccountExtension

Returns the “default value” for a type.

impl Hash for TransferHookAccountExtension

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TransferHookAccountExtension

fn eq(&self, other: &TransferHookAccountExtension) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
