My Statement -

Under the hood, Rust creates a hidden struct for each closure, holding captured variables and implementing the necessary traits.

Did you know? Rust can coerce non-capturing closures into function pointers. This special-case conversion allows closures to be used where function pointers are expected, as long as they don't capture state.

🚀 Dive into the Rust closures! Closures are anonymous functions that capture variables from their environment, making your code concise and flexible. Curious about how they work? Let's explore! #Rust

In most cases, you won't manually implement Fn, FnMut, or FnOnce. But if you want a custom struct to behave like a function, you can do so in nightly Rust using special features.

4. Inheritance in Rust? Not quite. Rust focuses on interfaces and implementations, with traits inheriting from other traits. #Programming #Rust

2. Methods in Rust aren't stored in structs. Instead, impl blocks define them. 3. Rust's polymorphism shines with traits. They act like interfaces, allowing shared behavior across different types without inheritance. #Rust

Let's explore OOPs in Rust! 🦀 Object-oriented programming (OOP) is all about objects, encapsulating data and behavior. Rust offers structs, impl blocks, and traits. 1. Encapsulation in Rust? Think structs! They bundle data like classes in other languages. #RUST

@sham_chandak @MeghUpdates Bademiya kabhi Gaye hai hum ?🧐

@MeghUpdates @siddharthqs

The Food and Drugs Administration (FDA) officials have yesterday shut down #Bademiya, a popular South Mumbai eatery, after cockroaches and rats were found in the kitchen during raids. A raid was carried out after several hygiene-related complaints.

The maximum point of pain is when you are badly beaten by the market, you finally give up and close your positions and the next day everything turns in your favor. Your big losses could have been profits. This is the pain.

After China had called on India to 'stay objective and calm' and avoid 'over-interpreting' the issue of the Chinese new map, India now published its own map.

Bruce Greenwald invited Li Lu to speak to his class on value investing. The result is a 90 minute masterclass on how to be a value investor. If you haven't watched the video, do it now. If you have, it's worth re-watching. Here is a list of my favorite quotes from Li Lu 👇 PERSONALITY OF A VALUE INVESTOR • "Understand who you are as an investor, because you will be tested. You will have to ask yourself if you truly are a value investor." • "Value investing goes against our evolution of following the crowds to survive." • "You will spend most of your time as an investigative journalist. To have insatiable curiosity." • "You almost have to be curious about everything. Because you never know where you'll get that one major insight." INVESTOR CRITERIA • Is it cheap? • Is it a good business? • Why is this opportunity available to me? "Once you answer those questions, you really have to go for it." INVESTMENT CASE STUDY 1: TIMBERLAND • "The first thing I check in a company is it's valuation." • "If you're an investor you don't care where it traded before." • "What matters isn't the price-to-book ratio itself, but what's in the book value." • "You want to compare the capital invested in the business to how much pre-tax cash flow the business generates using that capital." • "So Timberland generated $100M on $200M in capital invested. So why does the opportunity exist?" - Nike, Reebok, all the shoe brands fell off a cliff during the Asian Financial Crisis. - Founder owns 40% of the stock - Company was profitable and didn't need financial markets (no sell-side) - Tons of shareholder lawsuits • "What would be your conclusion if you were a normal mutual fund hearing this information? That management is milking the company for their own gain." What does Li Lu do next? • "I download every file of the shareholder court cases. That's the investigative journalist part." • "The result was that the founder withdrew guidance and shareholders didn't like it. That was it." How do you determine if management are decent people? • "You've got to be an investigative journalist and find the trail of evidence. Go to their community. Introduce yourself to their friends/family/neighbors." Total Time Commitment: "A couple of weeks of diligent/obsessive work" • "Investing is intensive work for short bursts of time." HOW MUCH TO BUY? • "If you go join a fund, they'll tell you not to risk anything more than 25-50bps." • "Think about how much effort you put in to this work. You have no downside and its trading at 5x profits." • "So, I put a shitload of money into Timberland. Over the next 10 years it went up 7x. It was never more than 15x earnings." • "If you're not a good analyst, you'll NEVER be a good investor." • "When it goes up, you don't have to do a damn thing. You just sit on it and ride with it." INVESTMENT CASE STUDY 2: KOREAN COMPANY • "Don't think about per-share numbers. Think of yourself as an owner." • "$236M in book value, $60M market cap, $25M net earnings." How do you know it's cheap? • "You must confirm that the earnings are there, and that the book value is real, liquid, and tangible." • "They're trading at the cash value in the bank with no debt. They have hotels and department stores that they own outright. They're making $30M+ in pre-tax earnings. And insiders own 50%." The result: Went up 5-6x VALUE INVESTING IS NOT NATURAL • "There's a lot of money in value investing. But it's still unnatural to most people." • "One thing you have to do, is you have to do the work. You have to do the reps. You can make a ton of money if you really do this stuff." • "I benefited by listening AND THEN DOING my own work. Making my own investments and mistakes." WHAT MAKES A GREAT ANALYST • "You must provide accurate and complete information. If you can't succeed on that, you can't succeed in this business." • "If you're not confident about your prediction and what you know, you can't put any money when the stock's in free fall." WHAT PROVIDES THE BIGGEST RETURNS • "Your biggest returns will come from no more than ten tremendous insights. That's it." • "The only way to build those insights is intense curiosity, intense study." INVESTING MISTAKES • "The biggest mistakes come when you buy before you've done all the work." • "My biggest mistakes aren't buying and losing money. It's not buying and missing out on 50-60x returns." HOW MANY COMPANIES SHOULD YOU BUY • "I don't have any set rules on how many stocks or companies I buy. Opportunities are sporadic and it depends on the environment." • "I usually have 3-4 big ideas. If the market is exciting, I have more opportunities. Or if the market is boring, I have fewer." HOW LI LU ALLOCATES TIME • "Most of the time I spend reading and studying about everything. Learning new companies and industries." • "If I find an idea that captivates me. I stop everything and obsess over that idea." • "Besides that, I spend a lot of time with my kid and my wife." TL;DR: • Be an investigative journalist. • Work obsessively in short bursts and spend the rest. of your time learning. • When you've done the work and have conviction, buy a shitload to make it worth it. • Before you invest $1, make sure you can answer the three big questions: Is it cheap, is the management team good, and why does the opportunity exist. • Never stop learning. • Become a curiosity machine.
