Struct TreeNode 

pub struct TreeNode {
    pub path: String,
    pub is_dir: bool,
    pub children: Option<Vec<TreeNode>>,
    pub summary: NodeSummary,
}

目录树节点

• 节点为文件时，无子树
• 节点为目录时，有子树

Fields

path: String

当前节点所处路径

is_dir: bool

是否是目录 TODO：后续应该改为自动检测

children: Option<Vec<TreeNode>>

如果是目录，那么遍历他的子节点；如果为文件，则为空

summary: NodeSummary

节点总结信息

• 文件：当前文件的总结信息
• 目录：当前目录下所有文件的总结信息的加合

Implementations

impl TreeNode

节点配置相关

pub fn new<P>(path: P, is_dir: bool) -> Self

where P: Into<String>,

创建一个项目树节点

Examples

use arui_core::tree::node::TreeNode;
let node = TreeNode::new("./src", true);

pub fn is_valid(&self) -> bool

检测节点路径是否合法

Examples

use arui_core::tree::node::TreeNode;

let valid = TreeNode::new("./src", true).is_valid();
assert_eq!(valid, true);

let in_valid = TreeNode::new("/not_exist", true).is_valid();
assert_eq!(in_valid, false);

impl TreeNode

为节点实现总结信息相关操作

pub fn upsert_summary(&mut self)

初次调用为获取节点总结信息 重复调用为更新节点总结信息，覆盖式更新当前节点的总结信息

Examples

use arui_core::tree::node::TreeNode;

// 初始化目录节点，无子节点
let mut folder_node = TreeNode::new("./src", true);
// 初始获取总结信息
folder_node.upsert_summary();
assert_eq!(folder_node.summary.size, 0);
assert_eq!(folder_node.summary.count, 0);

// 加入子节点
let sub_node = TreeNode::new("./src/lib.rs", false);
folder_node.children = Some(vec![sub_node]);
// 重复调用，覆盖式更新节点总结信息
folder_node.upsert_summary();
assert_eq!(folder_node.summary.size > 0, true);
assert_eq!(folder_node.summary.count > 0, true);

// 初始化文件节点
let mut file_node = TreeNode::new("./src/lib.rs", false);
file_node.upsert_summary();
assert_eq!(file_node.summary.size > 0, true);
assert_eq!(file_node.summary.count > 0, true);
