Struct guid::Guid

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

Windows format GUID.

Fields

data1: u32

data2: u16

data3: u16

data4: [u8; 8]

Implementations

impl Guid

pub fn new_random() -> Self

Return a new randomly-generated Version 4 UUID

pub const fn from_static_str(value: &'static str) -> Guid

Creates a new GUID from a string, panicking if the input is invalid. Accepted formats are “{00000000-0000-0000-0000-000000000000}” and “00000000-0000-0000-0000-000000000000”.

Note

This is a const function, intended to initialize GUID constants at compile time. While it can be used at runtime, it will panic if the input is invalid. For initializing non-constants, from_str should be used instead.

pub const ZERO: Self = _

The all-zero GUID.

pub fn is_zero(&self) -> bool

Returns true if this is the all-zero GUID.
