Struct framebuffer::FramebufferLocalControl

pub struct FramebufferLocalControl { /* private fields */ }

Used to control a framebuffer running in the same process

Implementations

impl FramebufferLocalControl

pub fn map(&mut self, gpa: u64, framebuffer_range: Option<MemoryRange>)

Maps the framebuffer to the guest at the specified GPA.

framebuffer_range is an optional subrange of the framebuffer to map.

pub fn unmap(&mut self)

Unmaps the framebuffer from the guest.

pub fn len(&self) -> usize

Returns the size of the framebuffer in bytes.

pub fn set_format(&mut self, format: FramebufferFormat)

Updates the framebuffer format.

pub fn memory(&self) -> Result<GuestMemory>

Gets a GuestMemory object that can be used to access the framebuffer memory.
