The Iterator trait in Rust defines how to loop through a sequence of values. If a type implements Iterator, you can use it with for loops, .next(), and many functional-style methods like map, filter, and fold. Every iterator has a…
Closures in Rust are anonymous functions that you can assign to variables, pass as arguments, and use just like regular functions. They can capture values from their environment, which makes them powerful for callbacks, iterators, and async workflows. The first…
Lifetimes in Rust tell the compiler how long references should remain valid. They prevent dangling pointers and invalid memory access without using a garbage collector. Rust infers lifetimes in most cases, but in some function and struct signatures, you must…
Trait bounds in Rust let you write generic code that only works for types with specific capabilities. You use T: Trait or where clauses to constrain what types are allowed. This helps you keep your code flexible but still type-safe.…
Traits in Rust are like interfaces in other languages. They define shared behavior that types can implement. You can use built-in traits like Debug, or define your own. Traits let you write code that works across different types, as long…
Rust allows you to write flexible and reusable code by using generic types in your functions and structs. You define generics with angle brackets like <T>, allowing your code to work across many types while staying safe and fast. A…
Rust and JavaScript are very different languages designed for different goals. Rust focuses on safety and performance with strong typing and no garbage collector, while JavaScript prioritizes flexibility and rapid development in the browser and beyond. If you are a…
Rust includes built-in tools to keep your code clean, readable, and consistent. Use rustfmt to format code automatically and clippy to catch common mistakes and bad practices. These tools help you write professional-grade code from day one. Recently, I noticed…
Rust supports two types of comments: normal inline (//) or multi-line (/* … */) for explaining your code, and special documentation comments that generate public-facing docs. Writing clear comments is key to keeping your Rust code readable and maintainable. One…
Rust has one of the most helpful compilers in any language. Its error messages are clear, actionable, and designed to teach. Still, as a beginner, compiler errors can feel overwhelming. Learning how to read and fix them is an essential…
