 </span><span class="doccomment">//! Generate and parse UUIDs.
 //!
 //! Provides support for Universally Unique Identifiers (UUIDs). A UUID is a
 //! unique 128-bit number, stored as 16 octets. UUIDs are used to  assign
 //! unique identifiers to entities without requiring a central allocating
 //! authority.
 //!
 //! They are particularly useful in distributed systems, though can be used in
 //! disparate areas, such as databases and network protocols.  Typically a UUID
 //! is displayed in a readable string form as a sequence of hexadecimal digits,
 //! separated into groups by hyphens.
 //!
 //! The uniqueness property is not strictly guaranteed, however for all
 //! practical purposes, it can be assumed that an unintentional collision would
 //! be extremely unlikely.
 //!
 //! # Dependencies
 //!
 //! By default, this crate depends on nothing but `std` and cannot generate
 //! UUIDs. You need to enable the following Cargo features to enable
 //! various pieces of functionality:
 //!
 //! * `v1` - adds the [`Uuid::new_v1`] function and the ability to create a V1
 //!   using an implementation of [`v1::ClockSequence`] (usually
 //! [`v1::Context`]) and a timestamp from `time::timespec`.
 //! * `v3` - adds the [`Uuid::new_v3`] function and the ability to create a V3
 //!   UUID based on the MD5 hash of some data.
 //! * `v4` - adds the [`Uuid::new_v4`] function and the ability to randomly
 //!   generate a UUID.
 //! * `v5` - adds the [`Uuid::new_v5`] function and the ability to create a V5
 //!   UUID based on the SHA1 hash of some data.
 //! * `serde` - adds the ability to serialize and deserialize a UUID using the
 //!   `serde` crate.
 //!
 //! For WebAssembly, enable one of the following features depending
 //! on your JavaScript interop toolchain of choice:
 //!
 //! * `stdweb` - for [`stdweb`] combined with [`cargo-web`]
 //! * `wasm-bindgen` - for [`wasm-bindgen`]
 //!
 //! By default, `uuid` can be depended on with:
 //!
 //! ```toml
 //! [dependencies]
 //! uuid = &quot;0.8&quot;
 //! ```
 //!
 //! To activate various features, use syntax like:
 //!
 //! ```toml
 //! [dependencies]
 //! uuid = { version = &quot;0.8&quot;, features = [&quot;serde&quot;, &quot;v4&quot;] }
 //! ```
 //!
 //! You can disable default features with:
 //!
 //! ```toml
 //! [dependencies]
 //! uuid = { version = &quot;0.8&quot;, default-features = false }
 //! ```
 //!
 //! # Examples
 //!
 //! To parse a UUID given in the simple format and print it as a urn:
 //!
 //! ```rust
 //! use uuid::Uuid;
 //!
 //! fn main() -&gt; Result&lt;(), uuid::Error&gt; {
 //!     let my_uuid =
 //!         Uuid::parse_str(&quot;936DA01F9ABD4d9d80C702AF85C822A8&quot;)?;
 //!     println!(&quot;{}&quot;, my_uuid.to_urn());
 //!     Ok(())
 //! }
 //! ```
 //!
 //! To create a new random (V4) UUID and print it out in hexadecimal form:
 //!
 //! ```ignore,rust
 //! // Note that this requires the `v4` feature enabled in the uuid crate.
 //!
 //! use uuid::Uuid;
 //!
 //! fn main() -&gt; Result&lt;(), Box&lt;dyn std::error::Error&gt;&gt; {
 //!     #[cfg(feature = &quot;v4&quot;)] {
 //!         let my_uuid = Uuid::new_v4()?;
 //!         println!(&quot;{}&quot;, my_uuid);
 //!     }
 //!     Ok(())
 //! }
 //! ```
 //!
 //! # Strings
 //!
 //! Examples of string representations:
 //!
 //! * simple: `936DA01F9ABD4d9d80C702AF85C822A8`
 //! * hyphenated: `550e8400-e29b-41d4-a716-446655440000`
 //! * urn: `urn:uuid:F9168C5E-CEB2-4faa-B6BF-329BF39FA1E4`
