Struct windows_core::GUID

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

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<Self>

Creates a unique GUID value.

pub const fn zeroed() -> Self

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

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

Creates a GUID with the given constant values.

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

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) -> Self

Creates a GUID for a “generic” WinRT type.
