Rust can be defined as a systems programming language that works at a very fast speed, manages and avoids segfaults, and confirms the safety of thread. The three goals on which Rust focuses include speed, concurrency, and safety.
These goals are maintained through the eradication of garbage collector, which makes this language useful for a number of cases.
History of Rust
Apart from the conventional static typing, typestates were also supported by the versions that came before version 0.4. The assertions were modelled prior to and after program statements, by the typestates system. This was done through the usage of a special check statement. The discrepancies were not discovered during program running, rather these were discovered at the time of compilation.
This marks a distinction between the assertions of Rust and C or C++ code. The concept of typestate, however, is not something unique to the Rust programming language. This is because it was first included in the NIL programming language. The reason behind the removal of typestates was low level of functionality of this concept on practical grounds, however, branding patterns can be used to increase the functionality of this concept.
Evident changes were made in the nature of object systems with the introduction of versions 0.2, 0.3 and 0.4. Classes were introduced initially by Version 0.2. Version 0.3, on the other hand, used interfaces to include a number of features, such as polymorphism and destructors, in the language. Rust 0.4, added traits to the language so as to introduce inheritance. In addition to that, structured types and implementations were also combined for the purpose of integration traits and interfaces.
~ and @, which are two pointer types, were built into the different versions of language from Rust 0.9 to Rust 0.11. These pointer types lead towards the simplification of core memory. In the year 2014, Andrew Binstock, who is the editor in chief of Dr Dobb’s Journal, indicated that Rust was a potential competitor of C++, as well as the other languages, Nim, D, and Go; that were yet to come. In the year 2015, Rust 10.0 was introduced. This was the first stable version of the language.
Rust attained the position of third most loved programming language in the Stack Overflow annual survey in the year 2015. The language managed to attain the first position, under the same head, in the 2016 Stack Overflow annual survey.
