Struct TrackedRef 

Source 
pub struct TrackedRef<'a, S> { /* private fields */ }
Expand description

A mutable reference to S with dirty tracking.

Like Tracked<S> but borrows instead of owning. Reading through read() or Deref does not set the dirty flag; writing through DerefMut does.

Implementations§

Source§

impl<'a, S> TrackedRef<'a, S>

Source

pub fn new(inner: &'a mut S) -> Self

Wrap a mutable reference, starting clean.

Source

pub fn is_dirty(&self) -> bool

Whether any mutation has occurred through DerefMut.

Source

pub fn read(&self) -> &S

Get a shared reference without marking dirty.

Trait Implementations§
