Struct smbioslib::SystemSlotId

pub struct SystemSlotId(pub [u8; 2]);

System Slots - Slot Id

The Slot ID field of the System Slot structure provides a mechanism to correlate the physical attributes of the slot to its logical access method (which varies based on the Slot Type field). The Slot ID field has meaning only for the slot types described in the table:

Slot Type	Slot ID Field Meaning
MCA	Identifies the logical Micro Channel slot number, in the range 1 to 15, in byte 0. Byte 1 is set to 0.
PCI, AGP, PCIX, PCI Express	On a system that supports ACPI, identifies the value returned in the _SUN object for this slot. On a system that supports the PCI IRQ Routing Table Specification, identifies the value present in the Slot Number field of the PCI Interrupt Routing table entry that is associated with this slot, in byte 0 - byte 1 is set to 0. The table is returned by the “Get PCI Interrupt Routing Options” PCI BIOS function call and provided directly in the PCI IRQ Routing Table Specification ($PIRQ). Software can determine the PCI bus number and device associated with the slot by matching the “Slot ID” to an entry in the routing-table and ultimately determine what device is present in that slot. NOTE: This definition also applies to the 66 MHz-capable PCI slots.
PCMCIA	Identifies the Adapter Number (byte 0) and Socket Number (byte 1) to be passed toPCMCIA Socket Services to identify this slot

Implementations

impl SystemSlotId

pub fn byte_0(&self) -> u8

The first system slot Id byte (found at offset 09h).

pub fn byte_1(&self) -> u8

The second system slot Id byte (found at offset 0Ah).

Methods from Deref<Target = [u8; 2]>

pub fn as_ascii(&self) -> Option<&[AsciiChar; N]>

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

Converts this array of bytes into a array of ASCII characters, or returns None if any of the characters is non-ASCII.

Examples

#![feature(ascii_char)]
#![feature(const_option)]

const HEX_DIGITS: [std::ascii::Char; 16] =
    *b"0123456789abcdef".as_ascii().unwrap();

assert_eq!(HEX_DIGITS[1].as_str(), "1");
assert_eq!(HEX_DIGITS[10].as_str(), "a");

pub unsafe fn as_ascii_unchecked(&self) -> &[AsciiChar; N]

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

Converts this array of bytes into a array of ASCII characters, without checking whether they’re valid.

Safety

Every byte in the array must be in 0..=127, or else this is UB.

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

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)]

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);

pub fn split_array_ref<const M: usize>(&self) -> (&[T; M], &[T])

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

Divides one array reference into two at an index.

The first will contain all indices from [0, M) (excluding the index M itself) and the second will contain all indices from [M, N) (excluding the index N itself).

Panics

Panics if M > N.

Examples

#![feature(split_array)]

let v = [1, 2, 3, 4, 5, 6];

{
   let (left, right) = v.split_array_ref::<0>();
   assert_eq!(left, &[]);
   assert_eq!(right, &[1, 2, 3, 4, 5, 6]);
}

{
    let (left, right) = v.split_array_ref::<2>();
    assert_eq!(left, &[1, 2]);
    assert_eq!(right, &[3, 4, 5, 6]);
}

{
    let (left, right) = v.split_array_ref::<6>();
    assert_eq!(left, &[1, 2, 3, 4, 5, 6]);
    assert_eq!(right, &[]);
}

pub fn rsplit_array_ref<const M: usize>(&self) -> (&[T], &[T; M])

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

Divides one array reference into two at an index from the end.

The first will contain all indices from [0, N - M) (excluding the index N - M itself) and the second will contain all indices from [N - M, N) (excluding the index N itself).

Panics

Panics if M > N.

Examples

#![feature(split_array)]

let v = [1, 2, 3, 4, 5, 6];

{
   let (left, right) = v.rsplit_array_ref::<0>();
   assert_eq!(left, &[1, 2, 3, 4, 5, 6]);
   assert_eq!(right, &[]);
}

{
    let (left, right) = v.rsplit_array_ref::<2>();
    assert_eq!(left, &[1, 2, 3, 4]);
    assert_eq!(right, &[5, 6]);
}

{
    let (left, right) = v.rsplit_array_ref::<6>();
    assert_eq!(left, &[]);
    assert_eq!(right, &[1, 2, 3, 4, 5, 6]);
}

Trait Implementations

impl Clone for SystemSlotId

fn clone(&self) -> SystemSlotId

Returns a copy of the value.
