WebbRust also has two primitive types for floating-point numbers, which are numbers with decimal points. Rust’s floating-point types are f32 and f64 , which are 32 bits and 64 bits in size, respectively. The default type is f64 because on modern CPUs it’s roughly the same speed as f32 but is capable of more precision. Webb29 nov. 2024 · Of the many ideas that Rust borrows from other languages, its enums are one that people seem to get the most excited about. They are sometimes referred to as sum types, algebraic data types, or tagged unions, and although they are typically associated with functional programming languages there’s nothing that precludes them …

It’s incredibly powerful and allows for type safety without nil-checking along with exhaustiveness checking. It’s extensively used in Swift.
WebbAlgebra of ADTs. Product types and sum types are collectively called “algebraic” data types because they have algebraic properties similar to normal integers. It’s a neat little construction that might help you understand the relation between products/sums, although it probably won’t change much in the design of your programs.
WebbAlgebraic Data Types. This section will introduce a feature of the PureScript type system called Algebraic Data Types (or ADTs), which are fundamentally related to pattern matching.
