Address lookup table metadata

Fields

deactivation_slot: u64

Lookup tables cannot be closed until the deactivation slot is no longer “recent” (not accessible in the SlotHashes sysvar).

last_extended_slot: u64

The slot that the table was last extended. Address tables may only be used to lookup addresses that were extended before the current bank’s slot.

last_extended_slot_start_index: u8

The start index where the table was last extended from during the last_extended_slot.

authority: Option<Pubkey>

Authority address which must sign for each modification.

_padding: u16

Implementations

impl LookupTableMeta

pub fn new(authority: Pubkey) -> LookupTableMeta

pub fn is_active(&self, current_slot: u64, slot_hashes: &SlotHashes) -> bool

Returns whether the table is considered active for address lookups

pub fn status( &self, current_slot: u64, slot_hashes: &SlotHashes ) -> LookupTableStatus

Return the current status of the lookup table

Trait Implementations

impl AbiExample for LookupTableMeta

fn example() -> LookupTableMeta

impl Clone for LookupTableMeta

fn clone(&self) -> LookupTableMeta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LookupTableMeta

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

Formats the value using the given formatter.

impl Default for LookupTableMeta

fn default() -> LookupTableMeta

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LookupTableMeta

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LookupTableMeta

fn eq(&self, other: &LookupTableMeta) -> 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.

impl Serialize for LookupTableMeta

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.
