pub fn device_type(&self) -> Option<&str>

pub fn remove_by_path(&mut self, path: &str) -> Result<Option<Node>, FdtError>

通过精确路径删除子节点及其子树 只支持精确路径匹配，不支持模糊匹配

参数

• path: 删除路径，格式如 “soc/gpio@1000” 或 “/soc/gpio@1000”

返回值

Ok(Option<Node>): 如果找到并删除了节点，返回被删除的节点；如果路径不存在，返回 None Err(FdtError): 如果路径格式无效

示例

let mut root = Node::new("");
// 添加测试节点
let mut soc = Node::new("soc");
soc.add_child(Node::new("gpio@1000"));
root.add_child(soc);

// 精确删除节点
let removed = root.remove_by_path("soc/gpio@1000")?;
assert!(removed.is_some());
