pub device: File,
pub frame: Mmap,
pub var_screen_info: VarScreeninfo,
pub fix_screen_info: FixScreeninfo,
}Struct that should be used to work with the framebuffer. Direct usage of frame should not be
necessary.
Fields
device: File
frame: Mmap
var_screen_info: VarScreeninfo
fix_screen_info: FixScreeninfo
Methods
impl Framebuffer[src]
fn new(path_to_device: &str) -> Result<Framebuffer, FramebufferError>
fn write_frame(&mut self, frame: &[u8])
Writes a frame to the Framebuffer.
fn get_fix_screeninfo(device: &File) -> Result<FixScreeninfo, FramebufferError>
Creates a FixScreeninfo struct and fills it using ioctl.
fn get_var_screeninfo(device: &File) -> Result<VarScreeninfo, FramebufferError>
Creates a VarScreeninfo struct and fills it using ioctl.
fn put_var_screeninfo(
device: &File,
screeninfo: &VarScreeninfo
) -> Result<i32, FramebufferError>
device: &File,
screeninfo: &VarScreeninfo
) -> Result<i32, FramebufferError>
fn set_kd_mode(kd_mode: KdMode) -> Result<i32, FramebufferError>
Sets the tty graphics mode. Make sure to change it back to KdMode::Text after the program is done!
