Struct InterruptCell

pub struct InterruptCell<T> { /* private fields */ }

A fast, thread-local cell that can be safely shared accross interrupt contexts

Warning

This cell must not be accessed from another thread; doing so will raise a panic.

Implementations

impl<T> InterruptCell<T>

pub const fn new_with_threadid(value: T, thread_id: usize) -> Self

Creates a new thread-local cell

pub fn new(value: T) -> Self

Creates a new thread-local cell

pub fn scope<F, FR>(&self, scope: F) -> FR

where F: FnOnce(&mut T) -> FR,

Provides scoped access to the underlying value

Panic

This function will panic if called from another thread or interrupt context

pub unsafe fn raw<F, FR>(&self, scope: F) -> FR

where F: FnOnce(&mut T) -> FR,

Provides an unsafe raw scoped access to the underlying value

Safety

This function provides unchecked, mutable access to the underlying value, so incorrect use of this function may lead to race conditions or undefined behavior.

impl<T> InterruptCell<LazyCell<T>>

pub fn lazy_scope<F, FR>(&self, scope: F) -> FR

where F: FnOnce(&mut T) -> FR,

Provides scoped access to the underlying lazy cell

Panic

This function will panic if called from another thread or interrupt context
