Struct fvm_ipld_amt::ValueMut

pub struct ValueMut<'a, V> { /* private fields */ }

A wrapper around a mutable reference to a value in an Amt. Keeps track of whether the value was mutated by setting a flag when DerefMut::deref_mut is called.

Implementations

impl<'a, V> ValueMut<'a, V>

pub fn new(value: &'a mut V) -> Self

pub fn value_changed(&self) -> bool

Trait Implementations

impl<V> Deref for ValueMut<'_, V>

type Target = V

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

Dereferences the value.

impl<V> DerefMut for ValueMut<'_, V>

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

Mutably dereferences the value.
