PointClickEngine::Core::Result(T, E)

Result type for operations that can succeed or fail

This provides a type-safe way to handle operations that might fail without relying on exceptions or nil returns. Inspired by Rust's Result type and functional programming error handling patterns.

Usage

def load_texture(path : String) : Result(Texture, AssetError)
  if File.exists?(path)
    texture = RL.load_texture(path)
    Result(T, E).success(texture)
  else
    Result(T, E).failure(AssetError.new("File not found", path))
  end
end

result = load_texture("sprite.png")
case result
when .success?
  texture = result.value
  # Use texture
when .failure?
  puts "Error: #{result.error.message}"
end
