Struct LogonGuid

pub struct LogonGuid {
    pub logon_guid: Uuid,
}

Fields

logon_guid: Uuid

Methods from Deref<Target = Uuid>

pub fn to_hyphenated_ref(&self) -> HyphenatedRef<'_>

Creates a HyphenatedRef instance from a Uuid reference.

pub fn to_simple_ref(&self) -> SimpleRef<'_>

Creates a SimpleRef instance from a Uuid reference.

pub fn to_urn_ref(&self) -> UrnRef<'_>

Creates a UrnRef instance from a Uuid reference.

pub const NAMESPACE_DNS: Uuid

pub const NAMESPACE_OID: Uuid

pub const NAMESPACE_URL: Uuid

pub const NAMESPACE_X500: Uuid

pub fn get_variant(&self) -> Option<Variant>

Returns the variant of the Uuid structure.

This determines the interpretation of the structure of the UUID. Currently only the RFC4122 variant is generated by this module.

• Variant Reference

pub fn get_version_num(&self) -> usize

Returns the version number of the Uuid.

This represents the algorithm used to generate the contents.

Currently only the Random (V4) algorithm is supported by this module. There are security and privacy implications for using older versions - see Wikipedia: Universally Unique Identifier for details.

• Version Reference

pub fn get_version(&self) -> Option<Version>

Returns the version of the Uuid.

This represents the algorithm used to generate the contents

pub fn as_fields(&self) -> (u32, u16, u16, &[u8; 8])

Returns the four field values of the UUID in big-endian order.

These values can be passed to the from_fields() method to get the original Uuid back.

• The first field value represents the first group of (eight) hex digits, taken as a big-endian u32 value. For V1 UUIDs, this field represents the low 32 bits of the timestamp.
• The second field value represents the second group of (four) hex digits, taken as a big-endian u16 value. For V1 UUIDs, this field represents the middle 16 bits of the timestamp.
• The third field value represents the third group of (four) hex digits, taken as a big-endian u16 value. The 4 most significant bits give the UUID version, and for V1 UUIDs, the last 12 bits represent the high 12 bits of the timestamp.
• The last field value represents the last two groups of four and twelve hex digits, taken in order. The first 1-3 bits of this indicate the UUID variant, and for V1 UUIDs, the next 13-15 bits indicate the clock sequence and the last 48 bits indicate the node ID.

Examples

use uuid::Uuid;

let uuid = Uuid::nil();
assert_eq!(uuid.as_fields(), (0, 0, 0, &[0u8; 8]));

let uuid = Uuid::parse_str("936DA01F-9ABD-4D9D-80C7-02AF85C822A8").unwrap();
assert_eq!(
    uuid.as_fields(),
    (
        0x936DA01F,
        0x9ABD,
        0x4D9D,
        b"\x80\xC7\x02\xAF\x85\xC8\x22\xA8"
    )
);

pub fn to_fields_le(&self) -> (u32, u16, u16, &[u8; 8])

Returns the four field values of the UUID in little-endian order.

The bytes in the returned integer fields will be converted from big-endian order.

Examples

use uuid::Uuid;

let uuid = Uuid::parse_str("936DA01F-9ABD-4D9D-80C7-02AF85C822A8").unwrap();
assert_eq!(
    uuid.to_fields_le(),
    (
        0x1FA06D93,
        0xBD9A,
        0x9D4D,
        b"\x80\xC7\x02\xAF\x85\xC8\x22\xA8"
    )
);

pub fn as_bytes(&self) -> &[u8; 16]

Returns an array of 16 octets containing the UUID data. This method wraps Uuid::as_bytes

pub fn to_timestamp(&self) -> Option<(u64, u16)>

Returns an Optional Tuple of (u64, u16) representing the timestamp and counter portion of a V1 UUID. If the supplied UUID is not V1, this will return None

pub fn is_nil(&self) -> bool

Tests if the UUID is nil
