Struct LocalCell

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

A fast, thread-local cell

§Warning

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

Implementations§

Source§

impl<T> LocalCell<T>

Source

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

Creates a new thread-local cell

Source

pub fn new(value: T) -> LocalCell<T>

Creates a new thread-local cell

Source

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

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> LocalCell<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
