[−]Struct asuran::IMPLEMENTATION_UUID
The UUID of this asuran implementation
Methods from Deref<Target = Uuid>
pub const fn to_hyphenated_ref(&self) -> HyphenatedRef
[src]
Get a borrowed HyphenatedRef
formatter.
pub const fn to_simple_ref(&self) -> SimpleRef
[src]
Get a borrowed SimpleRef
formatter.
pub const fn to_urn_ref(&self) -> UrnRef
[src]
Get a borrowed UrnRef
formatter.
pub const NAMESPACE_DNS: Uuid
[src]
pub const NAMESPACE_OID: Uuid

pub const NAMESPACE_X500: Uuid
[src]
pub fn get_variant(&self) -> Option<Variant>
[src]
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.
pub const fn get_version_num(&self) -> usize
[src]
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.
pub fn get_version(&self) -> Option<Version>
[src]
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])
[src]
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])
[src]
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_u128(&self) -> u128
[src]
Returns a 128bit value containing the UUID data.
The bytes in the UUID will be packed into a u128
, like the
Uuid::as_bytes
method.
Examples
use uuid::Uuid; let uuid = Uuid::parse_str("936DA01F-9ABD-4D9D-80C7-02AF85C822A8").unwrap(); assert_eq!( uuid.as_u128(), 0x936DA01F9ABD4D9D80C702AF85C822A8, )
pub fn to_u128_le(&self) -> u128
[src]
Returns a 128bit little-endian value containing the UUID data.
The bytes in the UUID will be reversed and packed into a u128
.
Note that this will produce a different result than
Uuid::to_fields_le
, because the entire UUID is reversed, rather
than reversing the individual fields in-place.
Examples
use uuid::Uuid; let uuid = Uuid::parse_str("936DA01F-9ABD-4D9D-80C7-02AF85C822A8").unwrap(); assert_eq!( uuid.to_u128_le(), 0xA822C885AF02C7809D4DBD9A1FA06D93, )
pub const fn as_bytes(&self) -> &[u8; 16]
[src]
Returns an array of 16 octets containing the UUID data.
pub fn is_nil(&self) -> bool
[src]
Tests if the UUID is nil.
