Module chromium 

Chromium helper transport, independent of native CEF build dependencies.

Modules

install

Asking the host to install the engine runtime.

runtime

Where the Chromium engine lives.

Structs

ChromiumEngine

A real Chromium process. Initialization errors are returned to the caller; this type never creates a simulated engine or weakens Chromium’s sandbox.

UnavailableEngine

Error-only surface used when the engine is not installed or cannot start. It never renders a page and answers navigation with its message, which is written for the person using the app.

Constants

PRIVATE_ROOT_HELPER

The engine helper’s pid, written once it runs inside the root.

PRIVATE_ROOT_LOCK

Writers hold this file shared and cleanup holds it exclusive.

PRIVATE_ROOT_MARKER

PRIVATE_ROOT_MARKER_CONTENT

PRIVATE_ROOT_PREFIX

A private window’s disposable root is a temp directory named with this prefix that holds PRIVATE_ROOT_MARKER reading PRIVATE_ROOT_MARKER_CONTENT; only such a root is ever removed.

Functions

is_owned_private_root

Whether root is a private window root Browser allocated: a real directory with the prefix and an intact marker, never a symlink.

release_private_root

Remove a private window’s disposable root that no engine will use, if it is one Browser owns.

serve_shared_until_idle

Blocks while other Browser processes still use a Chromium host this process runs, then stops serving them; a host none of this process’s engines still uses shuts down before this returns.
