Enum hotdrink_rs::builders::value_experiments::Value

pub enum Value<T> {
    Ref(Arc<T>),
    MutRef(Arc<RwLock<T>>),
}

A value in the constraint system.

Variants

Ref(Arc<T>)

A value that is only read.

MutRef(Arc<RwLock<T>>)

A value that is mutated in-place.

Implementations

impl<T> Value<T>

pub fn read(&self) -> ValueReadGuard<'_, T>

Returns a ValueReadGuard that provides an immutable reference to the inner value.

pub fn write(&self) -> Option<ValueWriteGuard<'_, T>>

Returns a ValueWriteGuard that provides a mutable reference to the inner value.

pub fn update(&mut self, new_value: T)

Updates the inner value of the Value. This should not change its writability.

pub fn is_mutable(&self) -> bool

Returns true if the inner value can be mutated in-place.

Trait Implementations

impl<T: Clone> Clone for Value<T>

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

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

Formats the value using the given formatter.

impl<T: Eq> Eq for Value<T>

impl<T: Eq> PartialEq<Value<T>> for Value<T>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]

pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
