Struct TokenMapHeader

#[repr(C)]
pub struct TokenMapHeader {
    pub store: Pubkey,
    /* private fields */
}

Header of TokenMap.

Fields

store: Pubkey

The authorized store.

Implementations

impl TokenMapHeader

pub fn space(num_configs: u8) -> usize

Get the space of the whole TokenMap required, excluding discriminator.

pub fn space_after_push(&self) -> Result<usize>

Get the space after push.

pub fn tokens(&self) -> impl Iterator<Item = Pubkey> + '_

Get tokens.

pub fn len(&self) -> usize

Get the number of tokens.

pub fn is_empty(&self) -> bool

Whether this token map is empty.

Trait Implementations

impl AccountDeserialize for TokenMapHeader

fn try_deserialize(buf: &mut &[u8]) -> Result<Self>

Deserializes previously initialized account data. Should fail for all uninitialized accounts, where the bytes are zeroed. Implementations should be unique to a particular account type so that one can never successfully deserialize the data of one account type into another. For example, if the SPL token program were to implement this trait, it should be impossible to deserialize a Mint account into a token Account.

fn try_deserialize_unchecked(buf: &mut &[u8]) -> Result<Self>

Deserializes account data without checking the account discriminator. This should only be used on account initialization, when the bytes of the account are zeroed.

impl Clone for TokenMapHeader

fn clone(&self) -> TokenMapHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TokenMapHeader

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

Formats the value using the given formatter.

impl Discriminator for TokenMapHeader

const DISCRIMINATOR: [u8; 8]

fn discriminator() -> [u8; 8]

impl Display for TokenMapHeader

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

Formats the value using the given formatter.

impl InitSpace for TokenMapHeader

const INIT_SPACE: usize = 8_556usize

Init Space.

impl Owner for TokenMapHeader

fn owner() -> Pubkey

impl Zeroable for TokenMapHeader

fn zeroed() -> Self

Calls zeroed.
