The set of global options supported by Servo. The values for these can be configured during initialization of Servo and cannot be changed later at runtime.

Fields

time_profiling: Option<OutputOptions>

None to disable the time profiler or Some to enable it with either:

• an interval in seconds to cause it to produce output on that interval.
• a file path to write profiling info to a TSV file upon Servo’s termination.

time_profiler_trace_path: Option<String>

When the profiler is enabled, this is an optional path to dump a self-contained HTML file visualizing the traces as a timeline.

hard_fail: bool

True to exit on thread failure instead of displaying about:failure.

debug: DiagnosticsLogging

Debug options that are used by developers to control Servo behavior for debugging purposes.

multiprocess: bool

Whether we’re running in multiprocess mode.

force_ipc: bool

Whether to force using ipc_channel instead of crossbeam_channel in singleprocess mode. Does nothing in multiprocess mode.

background_hang_monitor: bool

Whether we want background hang monitor enabled or not

sandbox: bool

Whether we’re running inside the sandbox.

random_pipeline_closure_probability: Option<f32>

Probability of randomly closing a pipeline, used for testing the hardening of the constellation.

random_pipeline_closure_seed: Option<usize>

The seed for the RNG used to randomly close pipelines, used for testing the hardening of the constellation.

shaders_path: Option<PathBuf>

Load shaders from disk.

config_dir: Option<PathBuf>

Directory for a default config directory

temporary_storage: bool

Use temporary storage (data on disk will not persist across restarts).

certificate_path: Option<String>

Path to PEM encoded SSL CA certificate store.

host_file: Option<PathBuf>

Path to a hosts file (like /etc/hosts). Ignored if the HOST_FILE environment variable is set.

ignore_certificate_errors: bool

Whether or not to completely ignore SSL certificate validation errors. TODO: We should see if we can eliminate the need for this by fixing https://github.com/servo/servo/issues/30080.

unminify_js: bool

Unminify Javascript.

local_script_source: Option<String>

Directory path that was created with “unminify-js”

unminify_css: bool

Unminify Css.
