sn0int - 半自动化 OSINT 框架和包管理器

OSINT 就是“公开资源情报”，常见于安全和黑客领域。这个 sn0int 是给 IT 安全专业人士和 bug 捕获者设计的 OSINT 框架及包管理器。它用于对给定的目标或你自己搜集情报，生成统一的格式，给后续的研究使用。

Rust 已经悄悄占领安全/黑客领域了。https://sn0int.readthedocs.io/en/stable/

insta - 快照测试库

Snapshots tests (also sometimes called approval tests) are tests that assert values against a reference value (the snapshot). This is similar to how assert_eq! lets you compare a value against a reference value but unlike simple string assertions snapshot tests let you test against complex values and come with comprehensive tools to review changes.

Snapshot tests are particularly useful if your reference values are very large or change often.

快照测试（有时也被称作赞成性测试）就是把值与一个引用值（快照）进行断言。有点像 assert_eq!。但是 assert_eq! 只是简单的字符串等类型的测试，快照测试支持进行复杂类型值的断言，并提供全面的功能进行更改校审。

快照测试在对值对象非常大或者改动非常频繁的时候，非常有用。

mobi-rs - 查看 .mobi 格式电子书的 Rust 库

可以解析和操作 .mobi 文件。比如：

use mobi::Mobi;
fn main() {
    let m = Mobi::init(Path::new("/home/wojtek/Downloads/lotr.mobi")).unwrap();
    let title = m.title().unwrap();
    let author = m.author().unwrap();
    let publisher = m.publisher().unwrap();
    let desc = m.description().unwrap();
    let isbn = m.isbn().unwrap();
    let pub_date = m.publish_date().unwrap();
    let contributor = m.contributor().unwrap();
    println!("{}\n{}\n{}\n{}\n{}\n{}\n{}\n", title, author, publisher, isbn, pub_date, desc, contributor);
}

luminance-rs - 类型安全/type-level和无状态的 Rust 图形框架

luminance 致力于让图形渲染变得简单优雅。它最初由 @phaazon 使用 Haskell 实现，在 2016 年的时候，移植到了 Rust 上面。

Where gfx-hal provides you with an experience focused on down-to-metal performance and an API very similar to Vulkan’s, luminance provides an API that is, for sure, a bit less low-level — and hence, yes, it’s likely you will not have the same performances as with gfx-hal (even though no benchmarks have been done so far), and the API is not Vulkan-based — but easier to start with, especially if you don’t already have a background experience with OpenGL or Vulkan.

icon-pie - 用命令行产生应用程序图标

用来将已有素材，转换，合成标准的 icon 规范的图标。像下面这样：

$ icon-pie -e small.svg 16 20 24 -e big.png 32 64 -ico output.ico
$ icon-pie -e image.png 32 64 48 -r linear -png output.tar
$ echo Here's an ICNS file: ${ icon-pie -e image.jpg 16 32 64 -r cubic -icns | hexdump }
