What is rust std?

The Rust standard library (also known as 'std') is a collection of modules that provide essential functionality for writing Rust programs. These modules include common data types such as strings, arrays, and iterators, along with various collections like vectors, hash maps, and linked lists.

The std library also provides system-level functionality like filesystem access, networking, and process management. Additionally, it includes support for threads, parallelism, and synchronization.

One notable aspect of the Rust std library is its reliance on the ownership and borrowing system, which promotes safe and efficient memory management. It also includes a robust set of error handling mechanisms, which can help developers avoid common pitfalls and write more reliable software.

Overall, the Rust std library is a crucial part of the Rust language ecosystem, providing a solid foundation for building high-quality applications and systems.
