Struct SharedCell

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

A cell that can be safely be shared across thread boundaries and interrupt contexts

Implementations

impl<T> SharedCell<T>

pub const fn new(value: T) -> Self

Creates a new cell

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

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

Provides scoped access to the underlying value

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> SharedCell<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
