Browser

Enum Browser

pub enum Browser {
    Chrome,
    Edge,
    Firefox,
    InternetExplorer,
    Opera,
    Safari,
}

Expand description

A browser family that AllowBrowser recognizes in the User-Agent header.

§Examples

use ocre::security::Browser;

let ua = "Mozilla/5.0 (Macintosh; Intel Mac OS X 14_4) AppleWebKit/605.1.15 (KHTML, like Gecko) \
          Version/17.4 Safari/605.1.15";
assert_eq!(Browser::detect(ua), Some((Browser::Safari, (17, 4))));
assert_eq!(Browser::detect("curl/8.7.1"), None);

Variants§

Chrome

Google Chrome and Chromium (Chrome/, CriOS/ on iOS).

Edge

Microsoft Edge (Edg/, EdgA/, EdgiOS/).

Firefox

Mozilla Firefox (Firefox/).

InternetExplorer

Internet Explorer (MSIE, Trident/).

Opera

Opera (OPR/).

Safari

Apple Safari (Version/... Safari/).

Implementations§

impl Browser

pub fn detect(user_agent: &str) -> Option<(Browser, (u32, u32))>

The browser and its (major, minor) version named by a User-Agent, or None for anything else (bots, curl).

Tokens are checked from the most specific: Edge and Opera also send Chrome/, and Chrome also sends Safari/. Pure CPU.

§Examples

use ocre::security::Browser;

let edge = "Mozilla/5.0 (Windows NT 10.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/124.0.0.0 \
            Safari/537.36 Edg/124.0.2478.51";
assert_eq!(Browser::detect(edge), Some((Browser::Edge, (124, 0))));
assert_eq!(Browser::detect("Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)"),
           Some((Browser::InternetExplorer, (8, 0))));
