Enum TokenDataVersion 

#[repr(u8)]
pub enum TokenDataVersion {
    V1 = 1,
    V2 = 2,
    ShaFlat = 3,
}

TokenDataVersion is recorded in the token account discriminator.

Variants

V1 = 1

V2 = 2

ShaFlat = 3

Implementations

impl TokenDataVersion

pub fn discriminator(&self) -> [u8; 8]

pub fn from_discriminator(discriminator: [u8; 8]) -> Result<Self, TokenError>

pub fn serialize_amount_bytes( &self, amount: u64, ) -> Result<[u8; 32], TokenError>

Serializes amount to bytes using version-specific endianness V1: little-endian, V2: big-endian

Trait Implementations

impl Clone for TokenDataVersion

fn clone(&self) -> TokenDataVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenDataVersion

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

Formats the value using the given formatter.

impl Hash for TokenDataVersion

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 TokenDataVersion

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

impl TryFrom<u8> for TokenDataVersion

type Error = TokenError

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.
