Struct bootloader::bootinfo::FrameRange

#[repr(C)]
pub struct FrameRange {
    pub start_frame_number: u64,
    pub end_frame_number: u64,
}

A range of frames with an exclusive upper bound.

Fields

start_frame_number: u64

The frame number of the first 4KiB frame in the region.

To convert this frame number to a physical address, multiply it with the page size (4KiB).

end_frame_number: u64

The frame number of the first 4KiB frame that does no longer belong to the region.

To convert this frame number to a physical address, multiply it with the page size (4KiB).

Implementations

impl FrameRange

pub fn new(start_addr: u64, end_addr: u64) -> Self

Create a new FrameRange from the passed start_addr and end_addr.

The end_addr is exclusive.

pub fn is_empty(&self) -> bool

Returns true if the frame range contains no frames.

pub fn start_addr(&self) -> u64

Returns the physical start address of the memory region.

pub fn end_addr(&self) -> u64

Returns the physical end address of the memory region.

Trait Implementations

impl Clone for FrameRange

fn clone(&self) -> FrameRange

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FrameRange

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FrameRange

fn eq(&self, other: &FrameRange) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
