Soenneker.Atomics.ValueInts

A lightweight, allocation-free atomic int struct backed by Volatile and Interlocked operations. Intended for use as a private field / inline synchronization primitive. Because this is a mutable struct, avoid copying it (e.g., returning it from properties or storing it in collections where it may be copied by value).

Install

dotnet add package Soenneker.Atomics.ValueInts

Usage

Use ValueAtomicInt as a field, not as a copied local value:

using Soenneker.Atomics.ValueInts;

public sealed class QueueMetrics
{
    private ValueAtomicInt _depth;

    public int Enqueued() => _depth.Increment();
    public int Dequeued() => _depth.Decrement();
    public int ReadDepth() => _depth.Read();
}

Because this is a mutable struct, returning it from a property or passing it by value creates an independent counter. Use the reference-type AtomicInt package when multiple objects must share the wrapper itself.

Update and Accumulate may invoke their delegate repeatedly during compare-and-exchange retries. Delegates must be side-effect free.

API at a glance

API	What it does	Result / important behavior
`ValueAtomicInt.Value`	Gets or sets the current value.	Gets or sets the current value.
`ValueAtomicInt.Read()`	Reads the current value using acquire semantics.	The current value observed with acquire memory-ordering semantics.
`ValueAtomicInt.Exchange(value)`	Atomically replaces the current value with `value` and returns the previous value.	The value that was stored before the atomic update.
`ValueAtomicInt.CompareExchange(value, comparand)`	Atomically sets the value to `value` if the current value equals `comparand`. Returns the original value.	The value observed before the compare-and-exchange attempt.
`ValueAtomicInt.TryCompareExchange(value, comparand)`	Attempts to set the value to `value` if the current value equals `comparand`.	true if the requested update was applied; otherwise, false.
`ValueAtomicInt.Increment()`	Atomically increments the value and returns the incremented value.	The incremented value.
`ValueAtomicInt.Decrement()`	Atomically decrements the value and returns the decremented value.	The decremented value.
`ValueAtomicInt.Add(delta)`	Atomically adds `delta` and returns the resulting value.	The resulting value.
`ValueAtomicInt.Or(mask)`	Atomically applies a bitwise OR mask.	The value observed before the OR operation. Read again when the resulting value is required.
`ValueAtomicInt.And(mask)`	Atomically applies a bitwise AND mask.	The value observed before the AND operation. Read again when the resulting value is required.
`ValueAtomicInt.GetAndIncrement()`	Atomically increments the value and returns the previous value.	The value that was stored before the atomic update.
`ValueAtomicInt.GetAndDecrement()`	Atomically decrements the value and returns the previous value.	The value that was stored before the atomic update.
`ValueAtomicInt.GetAndAdd(delta)`	Atomically adds `delta` and returns the previous value.	The value that was stored before the atomic update.
`ValueAtomicInt.AddAndGet(delta)`	Atomically adds `delta` and returns the resulting value.	The resulting value.
`ValueAtomicInt.IncrementAndGet()`	Atomically increments the value and returns the resulting value.	The resulting value.
`ValueAtomicInt.DecrementAndGet()`	Atomically decrements the value and returns the resulting value.	The resulting value.
`ValueAtomicInt.TrySetIfGreater(value)`	Attempts to set the value to `value` if it is greater than the current value.	true if the requested update was applied; otherwise, false.
`ValueAtomicInt.TrySetIfLess(value)`	Attempts to set the value to `value` if it is less than the current value.	true if the requested update was applied; otherwise, false.

Important behavior

ValueAtomicInt.Or(mask): This method returns the value from before the atomic update, matching Interlocked.Or semantics.
ValueAtomicInt.And(mask): This method returns the value from before the atomic update, matching Interlocked.And semantics.
ValueAtomicInt.VolatileWrite(value): Use this method to update the field in multithreaded scenarios where it is important that the most recent value is observed by all threads. This method provides a memory barrier to prevent certain types of reordering by the compiler or processor.
