20 Important Key Innovative Features of Rust
And How They Prevent Errors That Occur in Other Programming Languages
Introduction to Rust
Rust is a systems programming language that prioritizes safety and performance. Its unique ownership model, combined with strong type inference and pattern matching, allows developers to write robust applications while minimizing common programming errors. This article covers certain key features of Rust, providing explanations and code examples for each, illustrating how they help avoid mistakes that can occur in other programming languages.
1. Ownership
Ownership is the foundational concept in Rust, ensuring that each value has a single owner at any given time. This model prevents memory leaks and dangling pointers, common issues in languages like C and C++.
fn main() {
let s1 = String::from("Hello, Rust!"); // s1 owns the string
{
let s2 = s1; // Ownership of the string is moved to s2
println!("{}", s2); // s2 can be used
} // s2 goes out of scope, and the string is dropped
// println!("{}", s1); // This line would cause a compile-time error
}
In this example, s1
is a String
that owns the value "Hello, Rust!". When we assign s1
to s2
, ownership is…
