Enum RemoteDebugging 

#[non_exhaustive]
pub enum RemoteDebugging {
    Disabled,
    Port {
        port: u16,
        allowed_origins: Vec<String>,
    },
    Pipe,
}

Whether Chromium’s DevTools protocol server is reachable, and how.

This is the server behind chrome://inspect, not the DevTools window: it drives the browser from outside the process, so anything that can reach it can read and rewrite every page the application shows.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Disabled

No server. The runtime additionally pins Chromium’s devtools.remote_debugging.allowed preference off, so a --remote-debugging-port or --remote-debugging-pipe that reaches Chromium another way is refused too.

Port

Listen on a TCP port, as --remote-debugging-port does.

The port must be between 1024 and 65535; CEF ignores anything else. The port number is also written to DevToolsActivePort in the cache directory.

Chromium accepts a WebSocket connection from localhost and from any origin named in allowed_origins (--remote-allow-origins); leave that empty unless a browser page has to attach.

A listening port is reachable by every process on the machine, and the protocol has no authentication. Prefer Self::Pipe where the debugger is a child process.

Fields

port: u16

TCP port to listen on.

allowed_origins: Vec<String>

Origins allowed to open a WebSocket connection, beyond localhost.

Pipe

Speak the protocol over inherited file descriptors instead of a socket, as --remote-debugging-pipe does.

Reachable only by the process that launched this one, so it exposes nothing to the rest of the machine.
