}Expand description
A data structure that can be deserialized and stored into account storage,
i.e. an
AccountInfo’s
mutable data slice.
Required Methods§
Sourcefn try_deserialize_unchecked(buf: &mut &[u8]) -> Result<Self, Error>
fn try_deserialize_unchecked(buf: &mut &[u8]) -> Result<Self, Error>
Deserializes account data without checking the account discriminator. This should only be used on account initialization, when the bytes of the account are zeroed.
Provided Methods§
Sourcefn try_deserialize(buf: &mut &[u8]) -> Result<Self, Error>
fn try_deserialize(buf: &mut &[u8]) -> Result<Self, Error>
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.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
