Soenneker.Atomics.NullableBools

A lightweight atomic tri-state flag implemented on top of an inline ValueAtomicInt. Backing values: -1 = null / unknown 0 = false 1 = true.

Install

dotnet add package Soenneker.Atomics.NullableBools

Usage

The null state is useful for a value that has not been determined yet. TrySet lets one caller publish the first result:

using Soenneker.Atomics.NullableBools;

var availability = new AtomicNullableBool();

if (availability.TrySet(await ProbeAvailability()))
{
    // This caller published the transition from unknown to known.
}

bool? result = availability.Value;
availability.Reset();

GetValueOrFalse and GetValueOrTrue provide explicit fallback policies without changing the stored state.

Prefer the nullable Value, Set, TrySet, and Reset members in application code. Read, Write, and TryCompareExchange expose the raw representation (-1, 0, 1) and do not validate supplied integers; invalid raw values can produce misleading boolean and string results.

What you get

AtomicNullableBool — A lightweight atomic tri-state flag implemented on top of an inline ValueAtomicInt. Backing values: -1 = null / unknown 0 = false 1 = true.

API at a glance

API	What it does	Result / important behavior
`AtomicNullableBool.HasValue`	Gets a value indicating whether the current state is non-null.	Gets a value indicating whether the current state is non-null.
`AtomicNullableBool.Value`	Gets or sets the current value as a nullable boolean.	Gets or sets the current value as a nullable boolean.
`AtomicNullableBool.Read()`	Reads the raw backing state.	`-1` (null), `0` (false), or `1` (true).
`AtomicNullableBool.GetValueOrFalse()`	Gets the value, treating `null`/`unknown` as `false`.	true if gets the value, treating null/unknown as; otherwise, false.
`AtomicNullableBool.GetValueOrTrue()`	Gets the value, treating `null`/`unknown` as `true`.	true if gets the value, treating null/unknown as; otherwise, false.
`AtomicNullableBool.Set(value)`	Sets the state to `true` or `false`.	Returns no value; the requested change is complete when the method returns.
`AtomicNullableBool.TrySet(value)`	Attempts to set the state to `true` or `false` only if the current state is `null`/`unknown`.	true if the requested update was applied; otherwise, false.
`AtomicNullableBool.TryCompareExchange(newState, expected)`	Attempts to transition the state from `expected` to `newState`.	true if the requested update was applied; otherwise, false.
`AtomicNullableBool.Reset()`	Resets the state to `null`/`unknown`.	Returns no value; the requested change is complete when the method returns.
`AtomicNullableBool.ToString()`	Returns a string representation of the current state.	Returns `string`.

Important behavior

AtomicNullableBool: Reads establish acquire semantics and writes establish release semantics. This is a mutable reference type. Use as a private field and avoid exposing the instance publicly unless you want shared, aliasable state.
AtomicNullableBool.Write(state): Callers must only provide valid values: -1, 0, or 1.
