我正在尝试按照此Redis 文档链接创建一个可实时搜索的名人小型数据库（使用 Python 客户端）。

我尝试了类似的代码，但最后一行（按“s”查询）应该返回两个文档，而是返回一个空白集。有人可以帮我找出我所犯的错误吗？

我正在尝试Graph从 JSON 数据创建一个 petgraph 。JSON 包含图的边，键代表起始顶点，值是相邻顶点的列表。可以生成带有边向量的图。

我设法创建了一个Vec<(String, String))>但不是Vec<(&str, &str)>预期的。

extern crate petgraph;
extern crate serde_json;

use petgraph::prelude::*;
use serde_json::{Value, Error};

fn main() {
    let data = r#"{
      "A": [ "B" ],
      "B": [ "C", "D" ],
      "D": [ "E", "F" ]
    }"#;
    let json_value: Value = serde_json::from_str(data).unwrap();
    let mut edges: Vec<(String, String)> = vec![];
    if let Value::Object(map) = json_value {
        for (from_edge, array) in &map {
            if let &Value::Array(ref array_value) = array …
