Struct multiboot2_header::InformationRequestHeaderTag

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

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: [MbiTagTypeId; 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) -> [MbiTagTypeId; 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 const 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.

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

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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

fn cmp(&self, other: &InformationRequestHeaderTag<N>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

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

fn eq(&self, other: &InformationRequestHeaderTag<N>) -> 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.

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

fn partial_cmp( &self, other: &InformationRequestHeaderTag<N> ) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
