Grab-bag of configuration options for Carnelian apps.

Fields

keyboard_autorepeat: bool

Whether, when running without Scenic, this application should receive keyboard repeat events.

keyboard_autorepeat_slow_interval: Duration

The initial and maximum interval between keyboard repeat events, in milliseconds, when running without Scenic.

keyboard_autorepeat_fast_interval: Duration

The minimum interval between keyboard repeat events, in milliseconds, when running without Scenic.

use_spinel: bool

Whether to try to use hardware rendering (Spinel).

virtcon_mode: Option<VirtconMode>

What mode to use when acting as a virtual console.

view_mode: ViewMode

What sort of view system to use.

display_rotation: DisplayRotation

Application option to exercise transparent rotation.

keymap_name: Option<String>

Application option to select keymap. If named keymap is not found the fallback is US QWERTY.

display_resource_release_delay: Duration

How long should carnelian wait before releasing display resources when it loses ownership of the display while running directly on the display. The default value is five seconds, so that the resource will not be rapidly allocated and deallocated when switching quickly between virtcon and the regular display.

buffer_count: Option<usize>

In a bringup build the display coordinator might not support multiple buffers so Carnelian might have to run with only a single buffer. This configuration option is to allow testing rendering with a single buffer even in build that supports multiple.

input: bool

Whether input events are needed.

needs_blending: bool

Whether output can be translucent and needs blending.

startup_delay: Duration

How long to wait before entering event loop.
