Struct PerCpu 

pub struct PerCpu<T, S> { /* private fields */ }

Typed descriptor for one symbol replicated in every runtime CPU area.

Implementations

impl<T, S> PerCpu<T, S>

where S: PerCpuSymbol<T>,

pub fn offset(&self) -> usize

Returns this symbol’s byte offset in one area.

pub fn current_ptr(&self, pin: &CpuPin<'_>) -> NonNull<T>

Returns a typed pointer whose address is stable for pin.

pub fn remote_ptr(&self, area: PerCpuArea) -> NonNull<T>

Returns a typed pointer in an explicitly selected remote area.

The caller remains responsible for synchronization before dereference.

impl<T, S> PerCpu<T, S>

where S: PerCpuObjectSymbol<T>,

pub fn with_current_mut<R>( &self, exclusive: &ExclusiveCpu<'_>, operation: impl for<'value> FnOnce(&'value mut T) -> R, ) -> R

Mutates the current CPU’s object without allowing its borrow to escape.

impl<T, S> PerCpu<T, S>

where T: Sync, S: PerCpuObjectSymbol<T>,

pub fn with_current<R>( &self, pin: &CpuPin<'_>, operation: impl for<'value> FnOnce(&'value T) -> R, ) -> R

Borrows a shared current-CPU object for one non-escaping callback.

impl<T, S> PerCpu<T, S>

where T: Sealed, S: PerCpuPrimitiveSymbol<T>,

pub fn read_current(&self, pin: &CpuPin<'_>) -> T

Loads the current CPU’s atomic scalar with relaxed ordering.

pub fn write_current(&self, pin: &CpuPin<'_>, value: T)

Stores the current CPU’s atomic scalar with relaxed ordering.
