Implementations

impl UpgradeableLoaderState

pub fn buffer_len(program_len: usize) -> Result<usize, InstructionError>

Length of an buffer account’s data.

pub fn buffer_data_offset() -> Result<usize, InstructionError>

Offset into the ProgramData account’s data of the program bits.

pub fn program_len() -> Result<usize, InstructionError>

Length of an executable account’s data.

pub fn programdata_len(program_len: usize) -> Result<usize, InstructionError>

Length of a ProgramData account’s data.

pub fn programdata_data_offset() -> Result<usize, InstructionError>

Offset into the ProgramData account’s data of the program bits.

Trait Implementations

impl AbiExample for UpgradeableLoaderState

fn example() -> UpgradeableLoaderState

impl AccountDeserialize for UpgradeableLoaderState

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. Read more

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. Read more

fn try_serialize<W: Write>(&self, _writer: &mut W) -> Result<()>

Serializes the account data into writer.
