Struct PermanentDelegateAccountExtension 

#[repr(C)]
pub struct PermanentDelegateAccountExtension;

Marker extension indicating the account belongs to a mint with permanent delegate. This is a zero-size marker (no data) that indicates the token account’s mint has the SPL Token 2022 Permanent Delegate extension.

When present, token operations must check the SPL mint’s PermanentDelegate to determine the delegate authority before allowing transfers/burns.

Trait Implementations

impl BorshDeserialize for PermanentDelegateAccountExtension

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 PermanentDelegateAccountExtension

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 PermanentDelegateAccountExtension

fn clone(&self) -> PermanentDelegateAccountExtension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PermanentDelegateAccountExtension

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

Formats the value using the given formatter.

impl Default for PermanentDelegateAccountExtension

fn default() -> PermanentDelegateAccountExtension

Returns the “default value” for a type.

impl Hash for PermanentDelegateAccountExtension

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 PermanentDelegateAccountExtension

fn eq(&self, other: &PermanentDelegateAccountExtension) -> 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.
