Proposal: AsMaybeAsync

[mollsju]

Hello!
Any chance AsMaybeAsync could be added, just as we have ToResultAsync?

It would allow for less clutter when combined with EF.

Current:
Maybe<Entity> maybeEntity = (await dbContext.Entity.FirstOrDefaultAsync(x => x.Id == EntityId)).AsMaybe();

With AsMaybeAsync:
Maybe<Entity> maybeEntity = await dbContext.Entity.FirstOrDefaultAsync(x => x.Id == EntityId).AsMaybeAsync();

Yes, looks good. Feel free to submit a PR please.

perhaps include a implicit operator as well? i was working on a simular solution/problem.
Where I am calling a function that returns Result<T, TE>. But my method signature should return a Maybe. So in the case that result.isFailure it needs to convert. Now I have:

 public static async Task<Maybe<T>> ToMaybeAsync<T, TE>(this Task<Result<T, TE>> task) where T : class
 {
     var result = await task.ConfigureAwait(false);
     return result.IsSuccess ? Maybe<T>.From(result.Value) : Maybe<T>.None;
 }

But i guess the implicit converter would even be better.

 public static class MaybeExtensions
{
    // Implicit conversion operator from Result<T, TE> to Maybe<T>
    public static implicit operator Maybe<T>(Result<T, TE> result)
    {
        return result.IsSuccess ? Maybe<T>.From(result.Value) : Maybe<T>.None;
    }
}

I think i cannot add this directly in my code, can I?

The lack of the implicit conversion is intentional. Check out this article: https://khorikov.org/posts/2021-11-08-converting-result-to-maybe/
