MulticastFunc is a high-performance, drop-in alternative to Func that retrieves the return values of all invocations instead of only the final one.

Features

  • Familiar Syntax: Implements standard add/remove (+= / -=) operator behavior.
  • Thread-Safe: Immutable design guarantees safe concurrent execution.
  • Allocation-Free Overloads: Supports writing return values to a Span buffer.
  • Fault Tolerance: Optional execution path runs all delegates regardless of individual errors, throwing an aggregated exception at the end.
  • Native AOT: Native AOT compilation and trim compatible.

Usage Examples

Basic Mechanics
// Subscription
multicastFunc += MyMethod;
multicastFunc += () => "Hello World";

// Standard Invocation
string[]? results = multicastFunc?.Invoke();
Event Backing Field
public event Func<string> EventHappened
{
    add => multicastFunc += value;
    remove => multicastFunc -= value;
}
private MulticastFunc<string>? multicastFunc = default;
Advanced Execution Modes
// Fault-Tolerant: Invokes everything. Failing targets return default(T). Throws AggregateException.
string[]? results = multicastFunc?.InvokeAll();

// Allocation-Free: Write to a Span buffer for hot paths.
var buffer = ArrayPool<string>.Shared.Rent(multicastFunc.Count);
ReadOnlySpan<string> results = multicastFunc.Invoke(buffer);
