pub struct BootLoaderNameTag { /* private fields */ }
Expand description

The bootloader name tag.

Implementations§

source§

impl BootLoaderNameTag

source

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

source

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

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());
}

impl Pointee for BootLoaderNameTagwhere [u8]: Pointee,

§

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

The type for metadata in pointers and references to Self.
source§

impl TagTrait for BootLoaderNameTag

source§

const ID: TagType = TagType::BootLoaderName

The numeric ID of this tag.
source§

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. Read more
source§

fn as_base_tag(&self) -> &Tag

Returns the tag as the common base tag structure.
source§

fn size(&self) -> usize

Returns the total size of the tag. The depends on the size field of the tag.
source§

fn as_bytes(&self) -> &[u8]

Returns a slice to the underlying bytes of the tag. This includes all bytes, also for tags that are DSTs. The slice length depends on the size field of the tag.
source§

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. Read more
