Why Rust?

What makes Rust important?

We'll cover the following

Why Is Rust Different?

Why Is Rust Different? #

There are many reasons why Rust is different from other programming languages.

Speed #

Rust pays no penalty for the abstraction and only pays for the features that are actually used. This improves the code quality and readability without affecting the run time cost.

Safety #

Rust does not have a garbage collector. It ensures memory safety using ownership and its borrowing concept (discussed in the last chapter). The most significant difference between C, C++, and Rust is writing safe code. In Rust, the objects are managed by the programming language from the beginning to the end. The proper amount of memory required is allocated and automatically deallocated by the system when it is no longer in use.

Cargo Manager #

System languages like C and C++ never had a standard package manager. Rust provides a cargo manager that has all the rust libraries and frameworks to not only help developers make fantastic applications, but also distribute code to end-users.

Error Messages

The error messages in Rust are displayed using color. Formatting and misspellings in the program are commonly suggested. It not only displays the line which has the error but, also the type of error.

Efficient C Binding #

The Rust language can interoperate with the C language. It provides a foreign function interface to communicate with C API’s. Due to its ownership rules, it can guarantee memory safety.

Threads without Data Races

Data race is a condition where two or more threads can access the same memory location. Rust uses the concept of ownership to avoid data races.
