从此加入更多的行类型。
不能一次把所有的类型都加进去，因为语法识别之后还要做个修整才能转化。在此之前还要充分理解已有的代码。不知道要搞到什么时候。
测试代码如下：

// const LEFT: &str = "<";
// const RIGHT: &str = ">";
// const In: &str = "?";
// const Out：&str = "!";#[derive(Debug, Clone)]enum Line {PlaceHolder,Element { content: String },Comment { content: String },Rail { name: String, content: String },// Reference1 { pointer: String },// Reference2 { pointer: String, content: String },// Reference3 { pointer: String, content: String, lore: String },// Reference4 { name: String, pointer: String },// Reference5 { name: String, pointer: String, loer: String },Category1 { name: String },Category2 { name: String, content: String},// Category3 { name: String, pointer: String },// Category4 { name: String, pointer: String, lore: String },// Aggregate1 { name: String },// Aggregate2 { name: String, content: String },// Aggregate3 { name: String, pointer: String },// Aggregate4 { name: String, pointer: String, lore: String },// Aggregate5 { name: String }

测试结果与预期一致。
