Shared browser executable discovery engine and typed models used by the browser-locations family of crates.

cargo add browser-locations-core

Quick start

use browser_locations_core::{Browser, ReleaseChannel, locate_browser, discover_installed};

// locate a specific browser + channel
let edge = locate_browser(Browser::Edge, ReleaseChannel::Stable)?;
println!("{}", edge.path.display());

// discover every installed browser
for loc in discover_installed() {
    println!("{} {} -> {}", loc.browser, loc.channel, loc.path.display());
}
