CloneIterDebugMap

Struct CloneIterDebugMap 

Source
pub struct CloneIterDebugMap;
Expand description

用于克隆后迭代并格式化为调试映射的格式化处理器

这个结构体适配需要克隆才能迭代的集合,使用 debug_map() 方法将其格式化。

§类型参数

§示例

use wfu::{FmtBy, CloneIterDebugMap};
let range = (1..4).map(|i| (format!("key{}", i), i * 10));
let proxy = range.fmt_by(CloneIterDebugMap);
assert_eq!(format!("{:?}", proxy), r#"{"key1": 10, "key2": 20, "key3": 30}"#);

§注意
