Struct Guid 

pub struct Guid { /* private fields */ }

A Guid is a 16 byte Globally Unique Identifier.

Implementations

impl Guid

pub fn null() -> Guid

Return a null guid, i.e. 00000000-0000-0000-0000-000000000000

pub fn new() -> Guid

Creates a random Guid

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

Returns the bytes of the Guid

pub fn from_bytes(bytes: [u8; 16]) -> Guid

Creates a guid from a byte array.

pub fn from_slice(bytes: &[u8]) -> Result<Guid, Error>

Creates an UUID from a byte slice of exactly 16 bytes.

Trait Implementations

impl AsRef<[u8; 16]> for Guid

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

Converts this type into a shared reference of the (usually inferred) input type.

impl BinaryDecodable for Guid

fn decode<S>(stream: &mut S, _ctx: &Context<'_>) -> Result<Guid, Error>

where S: Read + ?Sized,

Decodes an instance from the read stream. The decoding options contains restrictions set by the server / client on the length of strings, arrays etc. If these limits are exceeded the implementation should return with a BadDecodingError as soon as possible.

impl BinaryEncodable for Guid

fn byte_len(&self, _ctx: &Context<'_>) -> usize

Returns the exact byte length of the structure as it would be if encode were called. This may be called prior to writing to ensure the correct amount of space is available.

fn encode<S>(&self, stream: &mut S, _ctx: &Context<'_>) -> Result<(), Error>

where S: Write + ?Sized,

Encodes the instance to the write stream.

fn override_encoding(&self) -> Option<BuiltInDataEncoding>

Override the extension object encoding used for this type. This only makes sense if the type can only ever be encoded using a single built-in encoding.

fn encode_to_vec(&self, ctx: &Context<'_>) -> Vec<u8>

Convenience method for encoding a message straight into an array of bytes. It is preferable to reuse buffers than to call this so it should be reserved for tests and trivial code.

impl Clone for Guid

fn clone(&self) -> Guid

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Guid

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Guid

fn default() -> Guid

Returns the “default value” for a type.

impl Display for Guid

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<Guid> for ByteString

fn from(value: Guid) -> ByteString

Converts to this type from the input type.

impl From<Guid> for DataValue

fn from(v: Guid) -> DataValue

Converts to this type from the input type.

impl From<Guid> for Identifier

fn from(v: Guid) -> Identifier

Converts to this type from the input type.

impl From<Guid> for NodeId

fn from(value: Guid) -> NodeId

Converts to this type from the input type.

impl From<Uuid> for Guid

fn from(uuid: Uuid) -> Guid

Converts to this type from the input type.

impl FromStr for Guid

type Err = <Uuid as FromStr>::Err

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Guid, <Guid as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for Guid

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IdentifierRef for &Guid

fn hash_as_identifier<H>(&self, state: &mut H)

where H: Hasher,

Hash the value as if it was in an identifier. This must result in the same hash as the equivalent identifier.

impl IdentifierRef for Guid

fn hash_as_identifier<H>(&self, state: &mut H)

where H: Hasher,

Hash the value as if it was in an identifier. This must result in the same hash as the equivalent identifier.

impl IntoVariant for Box<Guid>

fn into_variant(self) -> Variant

Convert self into a variant.

impl IntoVariant for Guid

fn into_variant(self) -> Variant

Convert self into a variant.

impl JsonDecodable for Guid

fn decode( stream: &mut JsonStreamReader<&mut dyn Read>, _ctx: &Context<'_>, ) -> Result<Guid, Error>

Decode Self from a JSON stream.

impl JsonEncodable for Guid

fn encode( &self, stream: &mut JsonStreamWriter<&mut dyn Write>, _ctx: &Context<'_>, ) -> Result<(), Error>

Write the type to the provided JSON writer.

impl PartialEq<[u8; 16]> for Guid

fn eq(&self, other: &[u8; 16]) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn eq(&self, other: &Guid) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
