Golang1.17源码分析之struct-004

源代码地址：reflect/type.go

数据结构：

// A StructField describes a single field in a struct.
type StructField struct {
	// Name is the field name.
	Name string

	// PkgPath is the package path that qualifies a lower case (unexported)
	// field name. It is empty for upper case (exported) field names.
	// See https://golang.org/ref/spec#Uniqueness_of_identifiers
	PkgPath string

	Type      Type      // field type
	Tag       StructTag // field tag string
	Offset    uintptr   // offset within struct, in bytes
	Index     []int     // index sequence for Type.FieldByIndex
	Anonymous bool      // is an embedded field
}

结构体内存对齐：根据成员的对其值，取最大的。然后最终结果要是对其边界的倍数，如果不够就会补全

int8 => 1 btye int16 => 2 byte
