}
struct DirNode{
name:String,
children:Vec<DirNode>,
}
1:#[derive(Serialize, Deserialize)]
Making serialize and deserialize for struct to json
2:struct DirNode{}
Making struct named DirNode
3:children:Vec
‘children’ retain subdirectory’s list.It means to make recursively storing a list of DirNode.
DirNode can contain multiple DirNode.
So ‘children’ can have subdirectories.
4:Vec
Making array can have multiple values by using heap allocation.
