Enum UserAgent

pub enum UserAgent {

Expand description

Represents different browser user agent strings for web scraping.

This enum provides a collection of realistic user agent strings from various browsers and operating systems. Using different user agents helps avoid being blocked by websites that restrict automated access.

§Examples

use markdown_harvest::UserAgent;

// Get a specific user agent
let chrome_windows = UserAgent::WindowsChrome;
println!("User-Agent: {}", chrome_windows.to_string());

// Get a random user agent for better diversity
let random_agent = UserAgent::random();
println!("Random User-Agent: {}", random_agent.to_string());

Implementations§

Source§

impl UserAgent

Source

pub fn to_string(&self) -> String

Converts the UserAgent enum variant to its corresponding user agent string.

Each variant returns a realistic, up-to-date user agent string that mimics real browsers. These strings include browser version numbers, operating system details, and rendering engine information.

§Returns

A String containing the complete user agent string for HTTP headers.

§Examples
use markdown_harvest::UserAgent;

let chrome = UserAgent::WindowsChrome;
let user_agent_string = chrome.to_string();
assert!(user_agent_string.contains("Chrome"));
assert!(user_agent_string.contains("Windows"));

let firefox = UserAgent::LinuxFirefox;
let user_agent_string = firefox.to_string();
assert!(user_agent_string.contains("Firefox"));
assert!(user_agent_string.contains("Linux"));
Source

pub fn random() -> UserAgent

Returns a random user agent for better web scraping diversity.

This method selects a random user agent from all available variants to help avoid detection and blocking by websites. Different user agents simulate requests from various browsers and operating systems.

§Returns

A randomly selected UserAgent variant. If random selection fails (which should never happen), defaults to UserAgent::LinuxFirefox.

§Examples
use markdown_harvest::UserAgent;

// Get different random user agents
let agent1 = UserAgent::random();
let agent2 = UserAgent::random();

// They might be different (but could be the same due to randomness)
println!("First random agent: {}", agent1.to_string());
println!("Second random agent: {}", agent2.to_string());

// Use in HTTP request
let random_agent = UserAgent::random();
let user_agent_header = random_agent.to_string();
// Use user_agent_header in your HTTP client...
