Length of a Buffer account’s data.

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

👎Deprecated since 1.11.0: Please use size_of_buffer_metadata instead

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

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

Trait Implementations

impl AbiExample for UpgradeableLoaderState

fn example() -> UpgradeableLoaderState

impl Clone for UpgradeableLoaderState

fn clone(&self) -> UpgradeableLoaderState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UpgradeableLoaderState

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for UpgradeableLoaderState

fn deserialize<__D>( __deserializer: __D, ) -> Result<UpgradeableLoaderState, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for UpgradeableLoaderState

fn eq(&self, other: &UpgradeableLoaderState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for UpgradeableLoaderState

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
