Struct TrackedField 

pub struct TrackedField<'s, T, F> { /* private fields */ }

A tracked field in a tracked struct which sets a flag when the value is changed.

Implementations

impl<'s, T, F> TrackedField<'s, T, F>

where F: Flags + Clone,

pub fn new(flag: F, track_flags: &'s mut F, value: &'s mut T) -> Self

Create a new tracked field

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

Forces an update, regardless of whether the value has changed.

pub fn update(&mut self, f: impl FnOnce(&mut T) -> bool) -> bool

Updates the value via a closure It should return true if the value has changed.

pub fn force_update(&mut self, f: impl FnOnce(&mut T))

Forces an update via a closure

pub fn update_opt(&mut self, f: impl FnOnce(&mut T) -> Option<T>) -> bool

Update with an option closure, only sets the flag is Some is returned useful for checked updates Returns true if the value was updated

impl<T, F> TrackedField<'_, T, F>

where T: PartialEq, F: Flags + Clone,

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

Set the value to the new one, but only set the flag whether the value changes

Trait Implementations

impl<T, F> AddAssign<T> for TrackedField<'_, T, F>

where T: AddAssign<T>, F: Flags + Clone,

fn add_assign(&mut self, rhs: T)

Performs the += operation.

impl<'s, T: Debug, F: Debug> Debug for TrackedField<'s, T, F>

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

Formats the value using the given formatter.

impl<T, F> Deref for TrackedField<'_, T, F>

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

Deref the Field value

type Target = T

The resulting type after dereferencing.

impl<T, F> DerefMut for TrackedField<'_, T, F>

where F: Flags + Clone,

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

Derefs the field value into a mutable reference but also marks the value as changed
