#[repr(C)]
pub struct TokenGroup {
    pub update_authority: OptionalNonZeroPubkey,
    pub mint: Pubkey,
    pub size: PodU32,
    pub max_size: PodU32,
}

Data struct for a TokenGroup

Fields

update_authority: OptionalNonZeroPubkey

The authority that can sign to update the group

mint: Pubkey

The associated mint, used to counter spoofing to be sure that group belongs to a particular mint

size: PodU32

The current number of group members

max_size: PodU32

The maximum number of group members

Implementations

impl TokenGroup

pub fn new( mint: &Pubkey, update_authority: OptionalNonZeroPubkey, max_size: u32 ) -> Self

Creates a new TokenGroup state

pub fn update_max_size(&mut self, new_max_size: u32) -> Result<(), ProgramError>

Updates the max size for a group

pub fn increment_size(&mut self) -> Result<u32, ProgramError>

Increment the size for a group, returning the new size

Trait Implementations

impl Clone for TokenGroup

fn clone(&self) -> TokenGroup

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenGroup

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

Formats the value using the given formatter.

impl Default for TokenGroup

fn default() -> TokenGroup

Returns the “default value” for a type.

impl PartialEq for TokenGroup

fn eq(&self, other: &TokenGroup) -> 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 SplDiscriminate for TokenGroup

const SPL_DISCRIMINATOR: ArrayDiscriminator = _

The 8-byte discriminator as a [u8; 8]

const SPL_DISCRIMINATOR_SLICE: &'static [u8] = _

The 8-byte discriminator as a slice (&[u8])

impl Zeroable for TokenGroup

fn zeroed() -> Self

Calls zeroed.

impl Copy for TokenGroup

impl Pod for TokenGroup

impl StructuralPartialEq for TokenGroup
