Struct solana_runtime::in_mem_accounts_index::PossibleEvictions

pub struct PossibleEvictions<T: IndexValue> {
    possible_evictions: Vec<FlushScanResult<T>>,
    index: usize,
}

Fields

possible_evictions: Vec<FlushScanResult<T>>

vec per age in the future, up to size ‘ages_to_stay_in_cache’

index: usize

next index to use into ‘possible_evictions’ if ‘index’ >= ‘possible_evictions.len()’, then there are no available entries

Implementations

impl<T: IndexValue> PossibleEvictions<T>

fn new(max_ages: Age) -> Self

fn get_possible_evictions(&mut self) -> Option<FlushScanResult<T>>

remove the possible evictions. This is required because we need ownership of the Arc strong counts to transfer to caller so entries can be removed from the accounts index

fn reset(&mut self, entries: Age)

clear existing data and prepare to add ‘entries’ more ages of data

fn insert( &mut self, relative_age: Age, key: Pubkey, entry: Arc<AccountMapEntryInner<T>>, random: bool )

insert ‘entry’ at ‘relative_age’ in the future into ‘possible_evictions’

Trait Implementations

impl<T: Debug + IndexValue> Debug for PossibleEvictions<T>

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

Formats the value using the given formatter.
