Struct Guid 

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

Binary-compatible with the GUID struct declared in com.h.

Fields

data1: u32

data2: u16

data3: u16

data4: [u8; 8]

Implementations

impl Guid

pub const ZERO: Guid

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

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

Builds a GUID from its 128-bit big-endian textual value, e.g. Guid::from_u128(0x809c652e_7396_11d2_9771_00a0c9b4d50c).

pub fn parse(s: &str) -> Option<Guid>

Parses xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx (braces optional).

pub const fn as_com_h_materialized(&self) -> Guid

The value native libraries built before the com.h fix materialize for this IID.

The __IID_DEF macro of com.h used to initialize Data4 as {d41, d42, d42, d42, d42, d42, d42, d42}: the second byte was repeated instead of using bytes 3..8. Native QueryInterface implementations memcmp against those constants, so an older native library answers this form; current ones answer the IDL value. Both are accepted and tried.
