Fields

program: LoadedProgramType

The program of this entry

account_size: usize

Size of account that stores the program and program data

deployment_slot: Slot

Slot in which the program was (re)deployed

effective_slot: Slot

Slot in which this entry will become active (can be in the future)

maybe_expiration_slot: Option<Slot>

Optional expiration slot for this entry, after which it is treated as non-existent

tx_usage_counter: AtomicU64

Implementations

impl LoadedProgram

pub fn new( loader_key: &Pubkey, program_runtime_environment: Arc<BuiltinProgram<InvokeContext<'static>>>, deployment_slot: Slot, effective_slot: Slot, maybe_expiration_slot: Option<Slot>, elf_bytes: &[u8], account_size: usize, metrics: &mut LoadProgramMetrics ) -> Result<Self, Box<dyn Error>>

Creates a new user program

pub fn to_unloaded(&self) -> Option<Self>

pub fn new_builtin( deployment_slot: Slot, account_size: usize, entrypoint: ProcessInstructionWithContext ) -> Self

Creates a new built-in program

pub fn new_tombstone(slot: Slot, reason: LoadedProgramType) -> Self

pub fn is_tombstone(&self) -> bool

Trait Implementations

impl AbiExample for LoadedProgram

fn example() -> Self

impl Debug for LoadedProgram

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

Formats the value using the given formatter.

impl Default for LoadedProgram

fn default() -> LoadedProgram

Returns the “default value” for a type.

impl PartialEq for LoadedProgram

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

This method tests for self and other values to be equal, and is used by ==.

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

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