go-interfaces

SKILL.md

Go's interfaces enable flexible, decoupled designs through implicit satisfaction and composition. This skill covers interface fundamentals, type inspection, and Go's approach to composition over inheritance.

Interfaces in Go specify behavior: if something can do this, it can be used here. Types implement interfaces implicitly—no implements keyword needed.

By convention, one-method interfaces use the method name plus -er suffix: Reader, Writer, Formatter, Stringer.

来自Effective Go 的Go 接口、类型断言、类型开关和嵌入。涵盖隐式接口满足、逗号惯用语、通过接口返回的通用性、用于组合的接口和结构嵌入。在定义或实现接口、使用类型断言/开关或通过嵌入组合类型时使用。 来源：cxuu/golang-skills。
