pub struct Zones<T, A: MemPool> { /* private fields */ }

Expand description

Memory Zones

It manages memory zones to optimally dedicate a zone to each cpu for scalability.

Implementations

source

impl<T, A: MemPool> Zones<T, A>

source

pub fn new(count: usize, offset: usize, quota: usize) -> Self

Creates a new Zones object

count is the number of zones (usually is the number cpus)
offset is the size of reserved memory to be allocated for metadata

source

pub fn quota(&self) -> usize

Returns the size of zones

source

pub fn count(&self) -> usize

Returns the number of zones

source

pub fn at(&self, i: usize) -> &mut T

Returns a mutable reference to the i-th zone object

source

pub fn get(&self) -> &mut T

Returns a mutable reference to the zone object associated with the current cpu

source

pub fn from_off(&self, off: u64) -> (&mut T, usize )

Returns a mutable reference to the zone object associated with the given offset
