securefmt

Debug derive宏的替换方案，隐藏标记为敏感的字段。

示例

以下代码片段

#[derive(Debug)]
struct SensitiveData {
    id: u8,
    #[sensitive]
    secret: u8
}

fn main() {
    println!("{:?}", SensitiveData { id: 1, secret: 42 })
}

将打印

SensitiveData { id: 1, secret: <redacted> }

如果[debug_mode]功能激活，则相同的代码将打印

WARN - WARNING: securefmt debug_mode feature is active. Sensitive data may be leaked. It is strongly recommended to disable debug_mode in production releases.
SensitiveData { id: 1, secret: 42 }
