Struct CompressedOnlyExtension 

#[repr(C)]
pub struct CompressedOnlyExtension {
    pub delegated_amount: u64,
    pub withheld_transfer_fee: u64,
    pub is_ata: u8,
}

CompressedOnly extension for compressed token accounts. This extension marks a compressed account as decompress-only (cannot be transferred). It stores the delegated amount from the source Token account when it was compressed-and-closed.

Fields

delegated_amount: u64

The delegated amount from the source Token account’s delegate field. When decompressing, the decompression amount must match this value.

withheld_transfer_fee: u64

Withheld transfer fee amount from the source Token account.

is_ata: u8

Whether the source was an ATA (1) or regular token account (0). When is_ata=1, decompress must verify ATA derivation matches.

Trait Implementations

impl BorshDeserialize for CompressedOnlyExtension

where u64: BorshDeserialize, 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 CompressedOnlyExtension

where u64: BorshSerialize, 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 CompressedOnlyExtension

fn clone(&self) -> CompressedOnlyExtension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressedOnlyExtension

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

Formats the value using the given formatter.

impl Hash for CompressedOnlyExtension

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 CompressedOnlyExtension

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

Configuration type needed to initialize this type

type Output = <CompressedOnlyExtension as ZeroCopyAtMut<'a>>::ZeroCopyAtMut

Output type - the mutable zero-copy view of this type

fn byte_len(config: &Self::ZeroCopyConfig) -> Result<usize, ZeroCopyError>

Calculate the byte length needed for this type with the given configuration

fn new_zero_copy( __remaining_bytes: &'a mut [u8], config: Self::ZeroCopyConfig, ) -> Result<(Self::Output, &'a mut [u8]), ZeroCopyError>
