TedToolkit.Scopes

A lightweight, high-performance ambient context (scope) library for .NET. Track contextual state through synchronous and asynchronous call chains with built-in Roslyn analyzers for performance guidance.

Quick Start

Implement IScope and push it onto the ambient context:

using TedToolkit.Scopes;

public class LogScope(string context) : IScope
{
    public string Context => context;
    public void OnEntry() { }
    public void OnExit()  { }
}

// Async method — use Push()
using (new LogScope("request").Push())
{
    var current = Scope<LogScope>.Current; // LogScope instance
    await HandleAsync();
}

// Sync method — use FastPush() for best performance
using (new LogScope("sync").FastPush())
{
    var current = FastScope<LogScope>.Current;
    Process();
}

Scope Types

Type Async-safe Constraint Backing
Scope<T> Yes class, IScope AsyncLocal
ValueScope<T> Yes struct, IScope AsyncLocal
FastScope<T> No IScope Thread-static stack
ScopeBase<T> Yes Inherit from it AsyncLocal
ScopeRecord<T> Yes Inherit from it AsyncLocal
  • Scope<T> / ValueScope<T> — Push via .Push(). Flows through async/await and Task.Run.
  • FastScope<T> — Push via .FastPush(). ref struct, cannot cross await boundaries. Best performance.
  • ScopeBase<T> / ScopeRecord<T> — Abstract base classes that auto-enter the scope on construction.

Unified Access

Use ScopeValues to read the current scope regardless of how it was pushed:

// Class scopes
LogScope? current = ScopeValues.Class<LogScope>.Current;

// Struct scopes
ref readonly TraceScope current = ref ScopeValues.Struct<TraceScope>.Current;

Analyzers

ID Title
SCOPE001 Suggests FastScope<T> instead of Scope<T>/ValueScope<T> in sync methods
SCOPE002 Suggests .FastPush() instead of .Push() in sync methods

Both include automatic code fixes.
