Trait Implementations

impl AccountDeserialize for EventQueue

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 EventQueue

fn clone(&self) -> EventQueue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Discriminator for EventQueue

const DISCRIMINATOR: [u8; 8] = _

fn discriminator() -> [u8; 8]

impl Owner for EventQueue

fn owner() -> Pubkey

impl Zeroable for EventQueue

fn zeroed() -> Self

Calls zeroed.
