Struct multiboot2_header::InformationRequestHeaderTag

#[repr(C, packed(8))]
pub struct InformationRequestHeaderTag<const N: usize> { /* fields omitted */ }

Specifies what specific tag types the bootloader should provide inside the mbi.

Implementations

impl<const N: usize> InformationRequestHeaderTag<N>

pub fn new(
    flags: HeaderTagFlag,
    requests: [MbiTagType; N],
    size: Option<u32>
) -> Self

Creates a new object. The size parameter is the value of the size property. It doesn’t have to match with N necessarily, because during compile time we can’t know the size of the tag in all runtime situations.

pub const fn typ(&self) -> HeaderTagType

pub const fn flags(&self) -> HeaderTagFlag

pub const fn size(&self) -> u32

pub const fn requests(&self) -> [MbiTagType; N]

Returns the requests as array. Only works if the number of requests is known at compile time. For safety and correctness during runtime, you should use req_iter().

pub const fn dynamic_requests_size(&self) -> u32

Returns the number of MbiTagType-requests derived from the size-property. This method is useful because this struct uses a const generic, but during runtime we don’t know the value in almost any case.

pub fn req_iter(&self) -> InformationRequestHeaderTagIter<'_>

Returns an InformationRequestHeaderTagIter.

Trait Implementations

impl<const N: usize> Clone for InformationRequestHeaderTag<N>

fn clone(&self) -> InformationRequestHeaderTag<N>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<const N: usize> Debug for InformationRequestHeaderTag<N>

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

Formats the value using the given formatter.
