Struct hyper_sardine::AuthId

pub struct AuthId(pub Uuid);

Methods from Deref<Target = Uuid>

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

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<UuidVersion>

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.

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

Returns an array of 16 octets containing the UUID data.

Examples

use uuid::Uuid;

let uuid = Uuid::nil();
assert_eq!(uuid.as_bytes(), &[0; 16]);

let uuid = Uuid::parse_str("936DA01F9ABD4d9d80C702AF85C822A8").unwrap();
assert_eq!(uuid.as_bytes(),
           &[147, 109, 160, 31, 154, 189, 77, 157,
             128, 199, 2, 175, 133, 200, 34, 168]);

pub fn simple(&self) -> Simple

Returns a wrapper which when formatted via fmt::Display will format a string of 32 hexadecimal digits.

Examples

use uuid::Uuid;

let uuid = Uuid::nil();
assert_eq!(uuid.simple().to_string(),
           "00000000000000000000000000000000");

pub fn hyphenated(&self) -> Hyphenated

Returns a wrapper which when formatted via fmt::Display will format a string of hexadecimal digits separated into groups with a hyphen.

Examples

use uuid::Uuid;

let uuid = Uuid::nil();
assert_eq!(uuid.hyphenated().to_string(),
           "00000000-0000-0000-0000-000000000000");

pub fn urn(&self) -> Urn

Returns a wrapper which when formatted via fmt::Display will format a string of the UUID as a full URN string.

Examples

use uuid::Uuid;

let uuid = Uuid::nil();
assert_eq!(uuid.urn().to_string(),
           "urn:uuid:00000000-0000-0000-0000-000000000000");

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
