Global flags for Servo, currently set on the command line.

Fields

legacy_layout: bool

Whether or not the legacy layout system is enabled.

tile_size: usize

The maximum size of each tile in pixels (-s).

time_profiling: Option<OutputOptions>

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

• an interval in seconds to cause it to produce output on that interval. (i.e. -p 5).
• a file path to write profiling info to a TSV file upon Servo’s termination. (i.e. -p out.tsv).

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.

mem_profiler_period: Option<f64>

None to disable the memory profiler or Some with an interval in seconds to enable it and cause it to produce output on that interval (-m).

nonincremental_layout: bool

True to turn off incremental layout.

userscripts: Option<String>

Where to load userscripts from, if any. An empty string will load from the resources/user-agent-js directory, and if the option isn’t passed userscripts won’t be loaded

user_stylesheets: Vec<(Vec<u8>, ServoUrl)>

output_file: Option<String>

headless: bool

hard_fail: bool

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

debug: DebugOptions

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

devtools_port: u16

Port number to start a server to listen to remote Firefox devtools connections. 0 for random port.

devtools_server_enabled: bool

Start the devtools server at startup

webdriver_port: Option<u16>

None to disable WebDriver or Some with a port number to start a server to listen to remote WebDriver commands.

initial_window_size: Size2D<u32, DeviceIndependentPixel>

The initial requested size of the window.

screen_size_override: Option<Size2D<u32, DeviceIndependentPixel>>

An override for the screen resolution. This is useful for testing behavior on different screen sizes, such as the screen of a mobile device.

multiprocess: bool

Whether we’re running 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.

exit_after_load: bool

True to exit after the page load (-x).

shaders_dir: Option<PathBuf>

Load shaders from disk.

config_dir: Option<PathBuf>

Directory for a default config directory

is_printing_version: bool

Print the version and exit.

certificate_path: Option<String>

Path to PEM encoded SSL CA certificate store.

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.

print_pwm: bool

Print Progressive Web Metrics to console.
