Struct hotdrink_rs::model::Variable

pub struct Variable<T> { /* fields omitted */ }

A variable that maintains its previous values.

Implementations

impl<T> Variable<T>

pub fn new(value: T) -> Self

Constructs a new Variable with the specified value.

pub fn set(&mut self, value: T)

Gives the variable a new value.

pub fn get(&self) -> &T

Returns a reference to the current value of the variable.

pub fn get_mut(&mut self) -> &mut T

Returns a mutable reference to the current value of the variable.

pub fn undo(&mut self) -> Result<(), NoMoreUndo>

Switches to the previous value of the variable.

pub fn redo(&mut self) -> Result<(), NoMoreRedo>

Switches to the next value of the variable.

Trait Implementations

impl<T: Clone> Clone for Variable<T>

fn clone(&self) -> Variable<T>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for Variable<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Default> Default for Variable<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> Deref for Variable<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for Variable<T>

fn deref_mut(&mut self) -> &mut Self::Target
