Struct cuckoocache::bitpacked::atomic::Flags

pub struct Flags { /* fields omitted */ }

Trait Implementations

impl FlagsT for Flags

const DEFAULT: bool

fn new(size: usize) -> Self

constructor creates memory to sufficiently keep track of garbage collection information for size entries.

fn setup(&mut self, b: usize)

setup marks all entries and ensures that bit_packed_atomic_flags can store at least size entries

fn bit_set(&mut self, s: usize)

bit_set sets an entry as discardable.

fn bit_unset(&mut self, s: usize)

bit_unset marks an entry as something that should not be overwritten

fn bit_set_to(&mut self, s: usize, discardable: bool)

bit_set_to sets an entry as specified. # Arguments * s the index of the entry to modify * discardable true does unset, false does set # Postconditions * immediately subsequent call (assuming proper external memory ordering) to bit_is_set(s) == true.

fn bit_is_set(&self, s: usize) -> bool

impl AtomicFlagsT for Flags

fn bit_set(&self, s: usize)

bit_set sets an entry as discardable.

Arguments

• s the index of the entry to bit_set @post immediately subsequent call (assuming proper external memory ordering) to bit_is_set(s) == true.

fn bit_unset(&self, s: usize)

bit_unset marks an entry as something that should not be overwritten

Arguments

• s the index of the entry to bit_unset @post immediately subsequent call (assuming proper external memory ordering) to bit_is_set(s) == false.
