Struct gpt_disk_types::Guid

#[repr(C)]
pub struct Guid {
    pub time_low: [u8; 4],
    pub time_mid: [u8; 2],
    pub time_high_and_version: [u8; 2],
    pub clock_seq_high_and_reserved: u8,
    pub clock_seq_low: u8,
    pub node: [u8; 6],
}

Globally-unique identifier.

The format is described in Appendix A of the UEFI Specification. Note that the first three fields are little-endian.

Fields

time_low: [u8; 4]

The little-endian low field of the timestamp.

time_mid: [u8; 2]

The little-endian middle field of the timestamp.

time_high_and_version: [u8; 2]

The little-endian high field of the timestamp multiplexed with the version number.

clock_seq_high_and_reserved: u8

The high field of the clock sequence multiplexed with the variant.

clock_seq_low: u8

The low field of the clock sequence.

node: [u8; 6]

The spatially unique node identifier.

Implementations

impl Guid

pub const ZERO: Guid = Self::new([0, 0, 0, 0], [0, 0], [0, 0], 0, 0, [0, 0, 0, 0, 0, 0])

GUID with all fields set to zero.

pub const fn new(
    time_low: [u8; 4],
    time_mid: [u8; 2],
    time_high_and_version: [u8; 2],
    clock_seq_high_and_reserved: u8,
    clock_seq_low: u8,
    node: [u8; 6]
) -> Guid

Create a new GUID.

pub const fn try_parse(s: &str) -> Result<Guid, GuidFromStrError>

Parse a GUID from a string.

This is functionally the same as Guid::from_str, but is exposed separately to provide a const method for parsing.

pub const fn from_bytes(bytes: [u8; 16]) -> Guid

Create a GUID from a 16-byte array. No changes to byte order are made.

pub const fn to_bytes(self) -> [u8; 16]

Convert to a 16-byte array.

pub const fn to_ascii_hex_lower(self) -> [u8; 36]

Convert to a lower-case hex ASCII string.

The output is in “xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx” format.
