Output — Results

use serde::{Deserialize, Serialize};

#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct Root {
    #[serde(rename = "id")]
    pub id: i64,
    #[serde(rename = "title")]
    pub title: String,
    #[serde(rename = "tags")]
    pub tags: Vec<String>,
    #[serde(rename = "active")]
    pub active: bool,
}
