system-config

一个 Rust 库，用于在任何上下文中以及在重启之间在磁盘上存储应用程序属性。

示例

将键值对添加到配置中，并将其写入磁盘...

let mut config = Config::new("system-config-example").unwrap();

config.insert("key1", "value1");
config.insert("key2", "value2");

config.write().unwrap();

然后可以在任何其他时间检索信息，即使在应用程序重启或在不同上下文中。

let config = Config::new("system-config-example").unwrap();

let key1 = config.get("key1").unwrap();
let key2 = config.get("key2").unwrap();

println!("key1: {}", key1);
println!("key2: {}", key2);

为了演示这一点，我创建了一些示例来执行这项操作。

$ cargo run -q --example write
$ cargo run -q --example read
key1: value1
key2: value2
$ cargo run -q --example clear
$ cargo run -q --example read
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', examples/read.rs:6:35
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

结构

内部，system-config 实际上是对 HashMap 的抽象，它读取和写入其信息，在每个 .read() 和 .write() 时以 yaml 格式写入磁盘。

该文件以 .yaml 格式写入您的配置目录中，由 dirs crate 找到。
