pub struct Uuid { bytes: UuidBytes, }
A Universally Unique Identifier (UUID)
impl Uuid
fn new_nil() -> Uuid
Returns a nil or empty UUID (containing all zeroes)
fn new(v: UuidVersion) -> std::option::Option
Create a new UUID of the specified version
fn new_v4() -> Uuid
Creates a new random UUID
Uses the rand
module's default RNG task as the source
of random numbers. Use the rand::Rand trait to supply
a custom generator if required.
fn from_fields(d1: u32, d2: u16, d3: u16, d4: &[u8]) -> Uuid
Creates a UUID using the supplied field values
d1
A 32-bit wordd2
A 16-bit wordd3
A 16-bit wordd4
Array of 8 octetsfn from_bytes(b: &[u8]) -> std::option::Option
Creates a UUID using the supplied bytes
b
An array or slice of 16 bytesfn get_variant(&self) -> std::option::Option
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.
fn get_version_num(&self) -> uint
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.
fn get_version(&self) -> std::option::Option
Returns the version of the UUID
This represents the algorithm used to generate the contents
fn to_bytes<'a>(&'a self) -> &'a [u8]
Return an array of 16 octets containing the UUID data
fn to_simple_str(&self) -> ~str
Returns the UUID as a string of 16 hexadecimal digits
Example: 936DA01F9ABD4d9d80C702AF85C822A8
fn to_hyphenated_str(&self) -> ~str
Returns a string of hexadecimal digits, separated into groups with a hypen
Example: 550e8400-e29b-41d4-a716-446655440000
fn to_urn_str(&self) -> ~str
Returns the UUID formatted as a full URN string
This is the same as the hyphenated format, but with the "urn:uuid:" prefix.
Example: urn:uuid:F9168C5E-CEB2-4faa-B6BF-329BF39FA1E4
fn parse_string(us: &str) -> std::result::Result
Parses a UUID from a string of hexadecimal digits with optional hyphens
Any of the formats generated by this module (simple, hyphenated, urn) are supported by this parsing function.
impl std::default::Default for Uuid
fn default() -> Uuid
Returns the nil UUID, which is all zeroes
impl std::num::Zero for Uuid
fn zero() -> Uuid
Returns the nil UUID, which is all zeroes
fn is_zero(&self) -> bool
Tests if the UUID is nil or all zeroes
impl std::clone::Clone for Uuid
fn clone(&self) -> Uuid
Returns a copy of the UUID
impl std::from_str::FromStr for Uuid
fn from_str(us: &str) -> std::option::Option
Parse a hex string and interpret as a UUID
Accepted formats are a sequence of 32 hexadecimal characters, with or without hypens (grouped as 8, 4, 4, 4, 12).
impl std::to_str::ToStr for Uuid
fn to_str(&self) -> ~str
impl std::cmp::Eq for Uuid
fn eq(&self, other: &Uuid) -> bool
impl std::cmp::TotalEq for Uuid
fn equals(&self, other: &Uuid) -> bool
impl std::rand::Rand for Uuid
fn rand<R: std::rand::Rng>(rng: &mut R) -> Uuid
Prefix searches with a type followed by a colon (e.g.
fn:
) to restrict the search to a given type.
Accepted types are: fn
, mod
,
struct
(or str
), enum
,
trait
, typedef
(or
tdef
).
