Struct multiboot2::BootLoaderNameTag

#[repr(C)]
pub struct BootLoaderNameTag { /* private fields */ }

The bootloader name tag.

Implementations

impl BootLoaderNameTag

pub fn new(name: &str) -> BoxedDst<Self>

pub fn name(&self) -> Result<&str, Utf8Error>

Reads the name of the bootloader that is booting the kernel as Rust string slice without the null-byte.

For example, this returns "GRUB 2.02~beta3-5".

If the function returns Err then perhaps the memory is invalid.

Examples

if let Some(tag) = boot_info.boot_loader_name_tag() {
    assert_eq!(Ok("GRUB 2.02~beta3-5"), tag.name());
}

Trait Implementations

impl Debug for BootLoaderNameTag

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

Formats the value using the given formatter.

impl Hash for BootLoaderNameTag

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

Feeds this value into the given [Hasher].

impl Ord for BootLoaderNameTag

fn cmp(&self, other: &BootLoaderNameTag) -> Ordering

This method returns an [Ordering] between self and other.

impl PartialEq for BootLoaderNameTag

fn eq(&self, other: &BootLoaderNameTag) -> 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 PartialOrd for BootLoaderNameTag

fn partial_cmp(&self, other: &BootLoaderNameTag) -> 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.

impl Pointee for BootLoaderNameTag

where [u8]: Pointee,

type Metadata = <[u8] as Pointee>::Metadata

The type for metadata in pointers and references to Self.

impl TagTrait for BootLoaderNameTag

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.

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.
