Soenneker.Atomics.Longs

A lightweight, allocation-free atomic long 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.Longs

Usage

using Soenneker.Atomics.Longs;

var bytesProcessed = new AtomicLong();

bytesProcessed.Add(buffer.Length);
long snapshot = bytesProcessed.Read();

Use SetIfGreater to retain a high-water mark under concurrency:

peakQueueDepth.SetIfGreater(currentQueueDepth);

TrySetIfGreater and TrySetIfLess perform one compare-and-exchange attempt; the retrying SetIfGreater and SetIfLess variants are preferable when the maximum or minimum must eventually reflect the supplied candidate.

Update and Accumulate run a compare-and-exchange loop and may call their delegate multiple times. The delegate must not perform logging, I/O, mutation, or other side effects.

All members operate atomically on this counter, but several separate calls are not one transaction. Use a lock when multiple values or multi-step invariants must change together.

API at a glance

API	What it does	Result / important behavior
`AtomicLong.Value`	Gets or sets the current value.	Gets or sets the current value.
`AtomicLong.Read()`	Reads the current value using acquire semantics.	The current value observed with acquire memory-ordering semantics.
`AtomicLong.Exchange(value)`	Atomically replaces the current value with `value` and returns the previous value.	The value that was stored before the atomic update.
`AtomicLong.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.
`AtomicLong.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.
`AtomicLong.Increment()`	Atomically increments the value and returns the incremented value.	The incremented value.
`AtomicLong.Decrement()`	Atomically decrements the value and returns the decremented value.	The decremented value.
`AtomicLong.Add(delta)`	Atomically adds `delta` and returns the resulting value.	The resulting value.
`AtomicLong.GetAndIncrement()`	Atomically increments the value and returns the previous value.	The value that was stored before the atomic update.
`AtomicLong.GetAndDecrement()`	Atomically decrements the value and returns the previous value.	The value that was stored before the atomic update.
`AtomicLong.GetAndAdd(delta)`	Atomically adds `delta` and returns the previous value.	The value that was stored before the atomic update.
`AtomicLong.AddAndGet(delta)`	Atomically adds `delta` and returns the resulting value.	The resulting value.
`AtomicLong.IncrementAndGet()`	Atomically increments the value and returns the resulting value.	The resulting value.
`AtomicLong.DecrementAndGet()`	Atomically decrements the value and returns the resulting value.	The resulting value.
`AtomicLong.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.
`AtomicLong.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.
`AtomicLong.SetIfGreater(value)`	Sets the value to `value` if it is greater than the current value, returning the effective value.	The effective value.
`AtomicLong.SetIfLess(value)`	Sets the value to `value` if it is less than the current value, returning the effective value.	The effective value.
