Trait Implementations§

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. Read more
Deserializes account data without checking the account discriminator. This should only be used on account initialization, when the bytes of the account are zeroed. Read more
Serializes the account data into writer.
Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes. Read more
Deserialize this instance from a slice of bytes.

Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
The type returned in the event of a conversion error.
