Struct CompressibleExtension 

#[repr(C)]
pub struct CompressibleExtension {
    pub decimals_option: u8,
    pub decimals: u8,
    pub compression_only: bool,
    pub is_ata: u8,
    pub info: CompressionInfo,
}

Compressible extension for token accounts. This extension contains compression configuration and timing data.

Fields

decimals_option: u8

Option discriminator for decimals (0 = None, 1 = Some)

decimals: u8

Token decimals (only valid when decimals_option == 1)

compression_only: bool

Whether this account is compression-only (cannot decompress)

is_ata: u8

Whether the source account is an ATA (1 = ATA, 0 = regular account) Used during compress_and_close to set is_ata in CompressedOnlyExtension

info: CompressionInfo

Compression configuration and timing data

Implementations

impl CompressibleExtension

pub const LEN: usize

impl CompressibleExtension

pub fn decimals(&self) -> Option<u8>

Returns the decimals if present

pub fn set_decimals(&mut self, decimals: Option<u8>)

Sets the decimals

Trait Implementations

impl BorshDeserialize for CompressibleExtension

where u8: BorshDeserialize, bool: BorshDeserialize, CompressionInfo: 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 CompressibleExtension

where u8: BorshSerialize, bool: BorshSerialize, CompressionInfo: 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 CompressibleExtension

fn clone(&self) -> CompressibleExtension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressibleExtension

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

Formats the value using the given formatter.

impl Hash for CompressibleExtension

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 CompressibleExtension

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

type Output = <CompressibleExtension 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>
