EdwardHsu.CircuitBreaker.HookInjector 1.0.2

EdwardHsu.CircuitBreaker

CircuitBreaker is a .NET library that provides a circuit breaker pattern implementation for methods. It is designed to prevent a method from being executed too frequently or too intensively, which can lead to resource exhaustion or other issues.

Features

• Circuit Breaker: The CircuitBreaker class represents the circuit breaker and provides methods to control its state (on, tripped off, and off).
• Fuse: The IFuse interface defines the triggering conditions of the circuit breaker. The library provides two implementations:
  • ExecutionLimitFuse: Trips the circuit breaker when the number of executions exceeds a specified limit.
  • TimeSlidingWindowLimitFuse: Trips the circuit breaker when the number of executions within a specified time window exceeds a limit.
• Injection: The CircuitBreakerHookInjector class allows you to inject the circuit breaker into existing methods without modifying the code.

Installation

#main package
dotnet add package EdwardHsu.CircuitBreaker

#hook injector package
dotnet add package EdwardHsu.CircuitBreaker.HookInjector

Usage

1. Create a Circuit Breaker.

var fuse = new ExecutionLimitFuse(5);
var breaker = new CircuitBreaker(fuse);

2. Execute a Method through the Circuit Breaker.

try
{
    breaker.Execute(new object[] { arg1, arg2 }); // Arguments can be passed to Fuse, which can determine whether to trigger based on these parameters.
}
catch (InvalidOperationException)
{
    // Circuit breaker is tripped off
}

3. Control the Circuit Breaker.

breaker.On(); // Turn on the circuit breaker
breaker.Off(); // Turn off the circuit breaker

4. Inject the Circuit Breaker into an Existing Method.

breaker.Inject(() => myInstance.MyMethod(arg));
breaker.Inject(() => MyClass.MyStaticMethod(arg));
