Reflections on Haskell and Rust

10 months ago

Professional experience with Haskell and Rust, focusing on web services and APIs.
Comparison of variable shadowing in Rust vs. Haskell, favoring Rust's readability.
Rust's enum system and pattern matching are more robust than Haskell's sum types.
Rust allows multiple enum types with the same variant names; Haskell requires unique names.
Rust provides granular visibility control for struct fields, unlike Haskell's all-or-nothing approach.
Haskell's commitment to purity and referential transparency is a significant strength.
Rust's explicit error handling with Result<T, E> is clearer than Haskell's potential exceptions.
Rust's built-in unit test support is more convenient than Haskell's separate test files.
Rust's rustfmt provides standardized formatting; Haskell lacks a single standard.
rust-analyzer offers a more reliable development experience than Haskell Language Server (HLS).
Rust's compilation times are consistently faster than Haskell's.
Haskell's REPL is superior for rapid prototyping; Rust lacks a native REPL.
Haskell's default list syntax can be inefficient; Rust encourages better alternatives.
TOML (Rust) offers better tooling and ecosystem support than Cabal (Haskell).
Rust services are easier to operate and deploy than Haskell services.
Rust's larger user base and active library ecosystem make it a pragmatic choice for many projects.
