pub struct Cell<T> {
priv value: Option<T>,
}impl<T> Cell<T>fn new(value: T) -> Cell<T>Creates a new full cell with the given value.
fn new_empty() -> Cell<T>Creates a new empty cell with no value inside.
fn take(&self) -> TYields the value, failing if the cell is empty.
fn take_opt(&self) -> Option<T>Yields the value if the cell is full, or None if it is empty.
fn put_back(&self, value: T)Returns the value, failing if the cell is full.
fn is_empty(&self) -> boolReturns true if the cell is empty and false if the cell is full.
fn with_ref<R>(&self, op: &fn(v: &T) -> R) -> RCalls a closure with a reference to the value.
fn with_mut_ref<R>(&self, op: &fn(v: &mut T) -> R) -> RCalls a closure with a mutable reference to the value.
impl<T: Clone> Clone for Cell<T>fn clone(&self) -> Cell<T>Returns a copy of the value. The contents of owned pointers are copied to maintain uniqueness, while the contents of managed pointers are not copied.
impl<T: DeepClone> DeepClone for Cell<T>fn deep_clone(&self) -> Cell<T>Return a deep copy of the value. Unlike Clone, the contents of shared pointer types
are copied.
impl<T: Eq> Eq for Cell<T>
Prefix searches with a type followed by a colon (e.g.
fn:) to restrict the search to a given type.
Accepted types are: fn, mod,
struct (or str), enum,
trait, typedef (or
tdef).
