字符串和迭代器

在本练习中，您将实现 Web 服务器的路由组件。服务器配置有多个路径前缀，这些前缀与请求路径匹配。路径前缀可以包含与完整段匹配的通配符。请参阅下面的单元测试。

将以下代码复制到 https://play.rust-lang.org/，然后设法通过测试。请尽量避免为中间结果分配“Vec”：

#![allow(unused)]
fn main() {
// TODO: remove this when you're done with your implementation.
#![allow(unused_variables, dead_code)]

pub fn prefix_matches(prefix: &str, request_path: &str) -> bool {
    unimplemented!()
}

#[test]
fn test_matches_without_wildcard() {
    assert!(prefix_matches("/v1/publishers", "/v1/publishers"));
    assert!(prefix_matches("/v1/publishers", "/v1/publishers/abc-123"));
    assert!(prefix_matches("/v1/publishers", "/v1/publishers/abc/books"));

    assert!(!prefix_matches("/v1/publishers", "/v1"));
    assert!(!prefix_matches("/v1/publishers", "/v1/publishersBooks"));
    assert!(!prefix_matches("/v1/publishers", "/v1/parent/publishers"));
}

#[test]
fn test_matches_with_wildcard() {
    assert!(prefix_matches(
        "/v1/publishers/*/books",
        "/v1/publishers/foo/books"
    ));
    assert!(prefix_matches(
        "/v1/publishers/*/books",
        "/v1/publishers/bar/books"
    ));
    assert!(prefix_matches(
        "/v1/publishers/*/books",
        "/v1/publishers/foo/books/book1"
    ));

    assert!(!prefix_matches("/v1/publishers/*/books", "/v1/publishers"));
    assert!(!prefix_matches(
        "/v1/publishers/*/books",
        "/v1/publishers/foo/booksByAuthor"
    ));
}
}
