Struct multiboot2::FramebufferTag
source · #[repr(C)]pub struct FramebufferTag { /* private fields */ }
Expand description
The VBE Framebuffer information tag.
Implementations§
source§impl FramebufferTag
impl FramebufferTag
pub fn new( address: u64, pitch: u32, width: u32, height: u32, bpp: u8, buffer_type: FramebufferType<'_> ) -> BoxedDst<Self>
sourcepub fn address(&self) -> u64
pub fn address(&self) -> u64
Contains framebuffer physical address.
This field is 64-bit wide but bootloader should set it under 4GiB if possible for compatibility with payloads which aren’t aware of PAE or amd64.
sourcepub fn buffer_type(&self) -> Result<FramebufferType<'_>, UnknownFramebufferType>
pub fn buffer_type(&self) -> Result<FramebufferType<'_>, UnknownFramebufferType>
The type of framebuffer, one of: Indexed
, RGB
or Text
.

source§fn dst_size(base_tag: &Tag) -> usize
fn dst_size(base_tag: &Tag) -> usize
Returns the amount of items in the dynamically sized portion of the
DST. Note that this is not the amount of bytes. So if the dynamically
sized portion is 16 bytes in size and each element is 4 bytes big, then
this function must return 4. Read more
source§fn as_base_tag(&self) -> &Tag
fn as_base_tag(&self) -> &Tag
Returns the tag as the common base tag structure.
source§fn size(&self) -> usize
fn size(&self) -> usize
Returns the total size of the tag. The depends on the
size
field of
the tag.source§fn as_bytes(&self) -> &[u8]
fn as_bytes(&self) -> &[u8]
Returns a slice to the underlying bytes of the tag. This includes all
bytes, also for tags that are DSTs. The slice length depends on the
size
field of the tag.source§unsafe fn from_base_tag<'a>(tag: &Tag) -> &'a Self
unsafe fn from_base_tag<'a>(tag: &Tag) -> &'a Self
Creates a reference to a (dynamically sized) tag type in a safe way.
DST tags need to implement a proper
Self::dst_size
implementation. Read more
