Struct SharedCell

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

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

Implementations§

Source§

impl<T> SharedCell<T>

Source

pub const fn new(value: T) -> SharedCell<T>

Creates a new cell

Source

pub fn scope<F, FR>(&self, scope: F) -> FR
where F: FnOnce(&mut T) -> FR,

Provides scoped access to the underlying value

Source

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.

Source§

impl<T> SharedCell<LazyCell<T>>

Source

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
