Struct FbDevOutputOptions 

pub struct FbDevOutputOptions {
    pub file_name: Option<String>,
    pub pixel_format: Option<PixelFormat>,
    pub render_directly_to_mapped_memory: bool,
    pub scaling: f64,
    pub use_async_front_buffer_blit: Option<bool>,
}

FbDev output options.

Fields

file_name: Option<String>

The frame buffer device name. Defaults to the value in the environment variable FRAMEBUFFER, or /dev/fb0 when FRAMEBUFFER is not set.

pixel_format: Option<PixelFormat>

The desired pixel format. When not set the format of the device is used.

render_directly_to_mapped_memory: bool

Render directly to the mapped memory of the device instead of to a back buffer that is copied after the vertical sync.

scaling: f64

The initial scale factor to use.

use_async_front_buffer_blit: Option<bool>

When true, the wait for the vertical sync and the copy that follows run on a dedicated thread, saving the rendering thread from a blocking wait. Only has an effect when render_directly_to_mapped_memory is false.
