This decouples your code from specific implementations, making it easier to test and extend. For example, a `User` struct might contain fields for `ID`, `Name`, and `Email`.
How Interface Satisfaction Decouples Code and Complements Struct Usage
This makes structs the go-to choice for managing state within an application. Therefore, performance-critical code often prefers concrete types to avoid the allocation and garbage collection pressure associated with interface usage.
You instantiate a struct to hold actual values, and you call its methods directly on that instance. Any type that implements those methods is said to satisfy the interface, allowing for polymorphism without inheritance.
How Interface Satisfaction Decouples Code and Enhances Struct Design
Practical Usage and Design Patterns In practice, the choice between an interface and a struct often dictates the architecture of your codebase. Interestingly, you can also embed interfaces to create more complex behavioral contracts.
