Key differences between Rust and Gleam

CharacteristicRustGleam
SyntaxC-like syntax with curly braces, explicit variable declarations, and pattern matching.Erlang/ML-inspired syntax, indentation-based, concise and functional.
ParadigmMulti-paradigm: systems programming, imperative, functional, and concurrent.Purely functional, designed for reliability and simplicity, targets BEAM VM.
TypingStatically typed with strong type inference and zero-cost abstractions.Statically typed with type inference, focuses on simplicity and safety.
PerformanceHigh performance, comparable to C/C++, suitable for low-level systems.Runs on BEAM VM, performance similar to Erlang/Elixir, optimized for concurrency, not raw speed.
Libraries and frameworksRich ecosystem with crates.io, mature libraries for web, networking, and systems.Smaller ecosystem, can use Erlang/Elixir libraries, but fewer native Gleam libraries.
Community and supportLarge, active community, strong documentation, and corporate backing.Growing but smaller community, good documentation, mostly grassroots support.
Learning curveSteep learning curve due to ownership, lifetimes, and advanced features.Gentle learning curve, simple syntax, and functional concepts, easier for beginners.
