Struct spl_token_2022::state::Mint

#[repr(C)]
pub struct Mint {
    pub mint_authority: COption<Pubkey>,
    pub supply: u64,
    pub decimals: u8,
    pub is_initialized: bool,
    pub freeze_authority: COption<Pubkey>,
}

Mint data.

Fields

mint_authority: COption<Pubkey>

Optional authority used to mint new tokens. The mint authority may only be provided during mint creation. If no mint authority is present then the mint has a fixed supply and no further tokens may be minted.

supply: u64

Total supply of tokens.

decimals: u8

Number of base 10 digits to the right of the decimal place.

is_initialized: bool

Is true if this structure has been initialized

freeze_authority: COption<Pubkey>

Optional authority to freeze token accounts.

Trait Implementations

impl BaseState for Mint

const ACCOUNT_TYPE: AccountType = AccountType::Mint

Associated extension type enum, checked at the start of TLV entries

impl Clone for Mint

fn clone(&self) -> Mint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Mint

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

Formats the value using the given formatter.

impl Default for Mint

fn default() -> Mint

Returns the “default value” for a type.

impl IsInitialized for Mint

fn is_initialized(&self) -> bool

Is initialized

impl Pack for Mint

const LEN: usize = 82usize

The length, in bytes, of the packed representation

fn get_packed_len() -> usize

Get the packed length

fn unpack(input: &[u8]) -> Result<Self, ProgramError>

where Self: IsInitialized,

Unpack from slice and check if initialized

fn unpack_unchecked(input: &[u8]) -> Result<Self, ProgramError>

Unpack from slice without checking if initialized

fn pack(src: Self, dst: &mut [u8]) -> Result<(), ProgramError>

Pack into slice

impl PackedSizeOf for Mint

const SIZE_OF: usize = 82usize

The packed size of the struct

impl PartialEq for Mint

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for Mint

impl Sealed for Mint
