Trait Implementations§
source§impl AccountDeserialize for EventQueue
impl AccountDeserialize for EventQueue
source§fn try_deserialize(buf: &mut &[u8]) -> Result<Self>
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
.source§fn try_deserialize_unchecked(buf: &mut &[u8]) -> Result<Self>
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.
