Struct Cell

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

Implementations

impl<T> Cell<T>

pub const fn new() -> Self

pub const fn new_with(init: T) -> Self

pub fn is_initialized(&self) -> bool

pub fn ref_num(&self) -> Result<usize, MemoryState>

pub fn try_take(&self) -> Result<Option<T>, Error<()>>

Takes ownership of the current value, leaving the cell uninitialized.

Returns Err if the cell is refered or in critical section.

pub fn take(&self) -> Result<Option<T>, Error<()>>

Takes ownership of the current value, leaving the cell uninitialized.

Returns Err is unreachable.

Notice: Spin

pub unsafe fn peek(&self) -> &T

pub fn try_get(&self) -> Result<Ref<'_, T>, Error<()>>

Tries to get a reference to the value of the Cell.

Returns Err if the cell is uninitialized, in operation or in critical section.

pub fn get(&self) -> Result<Ref<'_, T>, Error<()>>

Tries to get a reference to the value of the Cell.

Returns Err if the cell is uninitialized.

Notice: Spin

pub fn try_set(&self, value: T) -> Result<(), Error<T>>

Sets the value of the Cell to the argument value.

Returns Err if the value is refered, initialized or in critical section.

pub fn set(&self, value: T) -> Result<(), Error<T>>

Sets the value of the Cell to the argument value.

Returns Err if the value is refered, initialized.

Notice: Spin

pub fn try_replace(&self, value: T) -> Result<Option<T>, Error<T>>

Replaces the contained value with value, and returns the old contained value.

Returns Err if the value is refered or in critical section.

pub fn replace(&self, value: T) -> Result<Option<T>, Error<T>>

Replaces the contained value with value, and returns the old contained value.

Returns Err is unreachable.

Notice: Spin

pub fn get_or_try_init(&self, value: T) -> Result<Ref<'_, T>, Error<T>>

Tries to get a reference to the value of the Cell.

Returns Err if the cell is in critical section.

pub fn get_or_init(&self, value: T) -> Ref<'_, T>

Tries to get a reference to the value of the Cell.

Notice: Spin
