Structs

Structs and Enums in Solidity

Structs group related fields into custom record types, while enums give readable names to a fixed set of states — together they turn loose primitives into safe…

Structs and CLOS Basics

How defstruct gives you fast, simple record types, and how CLOS's classes, generic functions, and methods build on that foundation for object-oriented design.

Cell Arrays and Structs

Learn MATLAB's two containers for non-uniform data: cell arrays for heterogeneous collections, and structs for named-field records, including conversions betwe…

Custom Types and Structs

Learn how to define composite types with struct, control mutability and construction, use parametric fields for performance, and attach behavior via multiple d…

Structs in D

How D's value-type structs work: construction, methods, value-copy semantics, and the features that distinguish them from classes.

Structs in Elixir

Learn how Elixir structs extend maps with defined fields, compile-time checks, default values, and protocol-based behavior.

Structs in Go

A composite type that groups related fields together, forming the basis for custom data modeling in Go.

Structs in Rust

Structs let you group related values into a single named type with fields you access by name.

Structs in Swift

Structs are value types in Swift that are copied on assignment and come with a free memberwise initializer.

Structs vs Classes in Swift

Structs use value semantics while classes use reference semantics — the defining choice you make for every custom Swift type.

Swift Essentials for SwiftUI

The core Swift language features — structs, protocols, closures, optionals, and property wrappers — that every SwiftUI developer needs to be fluent in.

Go Structs & Methods Cheat Sheet

Explains defining Go structs, value versus pointer method receivers, struct embedding for composition, and how Go achieves reuse without inheritance.
