Erlang vs Rust: What are the differences?
Developers describe Erlang as "A programming language used to build massively scalable soft real-time systems with requirements on high availability". Some of Erlang's uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. OTP is set of Erlang libraries and design principles providing middle-ware to develop these systems. On the other hand, Rust is detailed as "A safe, concurrent, practical language". Rust is a systems programming language that combines strong compile-time correctness guarantees with fast performance. It improves upon the ideas of other systems languages like C++ by providing guaranteed memory safety (no crashes, no data races) and complete control over the lifecycle of memory.
Erlang and Rust belong to "Languages" category of the tech stack.
"Real time, distributed applications" is the top reason why over 49 developers like Erlang, while over 81 developers mention "Guaranteed memory safety" as the leading cause for choosing Rust.
Erlang and Rust are both open source tools. Rust with 37.3K GitHub stars and 5.85K forks on GitHub appears to be more popular than Erlang with 7.74K GitHub stars and 2.1K GitHub forks.
According to the StackShare community, Rust has a broader approval, being mentioned in 39 company stacks & 105 developers stacks; compared to Erlang, which is listed in 70 company stacks and 47 developer stacks.
