Struct GUID

#[repr(C)]
pub struct GUID {
    pub data1: u32,
    pub data2: u16,
    pub data3: u16,
    pub data4: [u8; 8],
}

A globally unique identifier (GUID) used to identify COM and WinRT interfaces.

Fields

data1: u32

Specifies the first 8 hexadecimal digits.

data2: u16

Specifies the first group of 4 hexadecimal digits.

data3: u16

Specifies the second group of 4 hexadecimal digits.

data4: [u8; 8]

The first 2 bytes contain the third group of 4 hexadecimal digits. The remaining 6 bytes contain the final 12 hexadecimal digits.

Implementations

impl GUID

pub fn new() -> Result<GUID, Error>

Creates a unique GUID value.

pub const fn zeroed() -> GUID

Creates a GUID represented by the all-zero byte-pattern.

pub const fn from_values( data1: u32, data2: u16, data3: u16, data4: [u8; 8], ) -> GUID

Creates a GUID with the given constant values.

pub const fn from_u128(uuid: u128) -> GUID

Creates a GUID from a u128 value.

pub const fn to_u128(&self) -> u128

Converts a GUID to a u128 value.

pub const fn from_signature(signature: ConstBuffer) -> GUID

Creates a GUID for a “generic” WinRT type.

Trait Implementations

impl Clone for GUID

fn clone(&self) -> GUID

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GUID

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

Formats the value using the given formatter.

impl Default for GUID

fn default() -> GUID

Returns the “default value” for a type.

impl From<u128> for GUID

fn from(value: u128) -> GUID

Converts to this type from the input type.

impl Hash for GUID

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

where __H: Hasher,

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 PartialEq for GUID

fn eq(&self, other: &GUID) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&str> for GUID

type Error = Error

The type returned in the event of a conversion error.

fn try_from(from: &str) -> Result<GUID, Error>

Performs the conversion.

impl Copy for GUID

impl Eq for GUID

impl StructuralPartialEq for GUID
