Implementations§

source§

impl Info

source

pub unsafe fn from_ptr(ptr: *const u8) -> &'static Self

Parses the Multiboot information structures

source

pub fn memory(&self) -> Option<&Memory>

Returns the memory sizes

source

pub fn boot_device(&self) -> Option<&BootDevice>

Indicates which bios disk device the boot loader loaded the OS image from.

source

pub fn cmdline(&self) -> Option<&str>

Command line to be passed to the kernel.

source

pub fn boot_loader_name(&self) -> Option<&str>

Get the name of the bootloader.

source

pub fn modules(&self) -> Option<&[Module]>

Discover all additional modules in multiboot.

source

pub fn symbols(&self) -> Option<Symbols>

Get the symbols.

source

pub fn memory_map(&self) -> Option<MemoryMapIter<'_>>

Discover all memory regions in the multiboot memory map.

source

pub fn find_highest_address(&self) -> u32

Return end address of multiboot image.

This function can be used to figure out a (hopefully) safe offset in the first region of memory to start using as free memory.

source

pub fn vbe(&self) -> Option<&VBETable>

Contains the VESA BIOS extensions

source

pub fn framebuffer(&self) -> Option<&FramebufferTable>

Contains the information about the framebuffer
