Struct smbioslib::Header

pub struct Header(_);

SMBIOS Header

The header part/section of a structure

Implementations

impl Header

pub const SIZE: usize

Total size of a Header (4)

A header has a byte for the struct_type at offset 0, a byte for the length at offset 1, and a word for the handle at offset 2 for a total of 4 bytes.

pub const STRUCT_TYPE_OFFSET: usize

StructType offset (offset 0 and 1 bytes)

pub const LENGTH_OFFSET: usize

Length offset (offset 1 and 1 bytes)

pub const HANDLE_OFFSET: usize

Handle offset (offset 2 and 2 bytes)

pub fn new(data: [u8; 4]) -> Self

Creates a new Header struct

pub fn struct_type(&self) -> u8

The type of SMBIOS structure

pub fn length(&self) -> u8

The length of the structure not including the strings part/section

pub fn handle(&self) -> Handle

The handle of this structure instance

pub fn iter(&self) -> Iter<'_, u8>

Byte iterator of the header

Methods from Deref<Target = [u8; 4]>

pub fn as_slice(&self) -> &[T]

🔬 This is a nightly-only experimental API. (array_methods)

Returns a slice containing the entire array. Equivalent to &s[..].

pub fn each_ref(&self) -> [&T; N]

🔬 This is a nightly-only experimental API. (array_methods)

Borrows each element and returns an array of references with the same size as self.

Example

#![feature(array_methods)]

let floats = [3.1, 2.7, -1.0];
let float_refs: [&f64; 3] = floats.each_ref();
assert_eq!(float_refs, [&3.1, &2.7, &-1.0]);

This method is particularly useful if combined with other methods, like map. This way, you can avoid moving the original array if its elements are not Copy.

#![feature(array_methods, array_map)]

let strings = ["Ferris".to_string(), "♥".to_string(), "Rust".to_string()];
let is_ascii = strings.each_ref().map(|s| s.is_ascii());
assert_eq!(is_ascii, [true, false, true]);

// We can still access the original array: it has not been moved.
assert_eq!(strings.len(), 3);

Trait Implementations

impl Debug for Header

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

Formats the value using the given formatter.

impl Deref for Header

type Target = [u8; 4]

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<[u8; 4]> for Header

fn from(data: [u8; 4]) -> Self

Performs the conversion.
