Struct fdb_rl_proto::fdb_rl::field::v1::Uuid

pub struct Uuid {
    pub value: Bytes,
}

Java RecordLayer defines this type using two sfixed64 fields. In Java, UUID class consists of two long values [1], so it makes sense to use sfixed64.

In our case, we use uuid::Uuid which uses type Bytes = \[u8; 16\] internally [2]. So, we use Protobuf bytes type internally in UUID. From this [3] comment, it looks like Google uses bytes and string for UUID.

Trait Implementations

impl Clone for Uuid

fn clone(&self) -> Uuid

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Uuid

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

Formats the value using the given formatter.

impl Default for Uuid

fn default() -> Self

Returns the “default value” for a type.

impl Message for Uuid

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8, Global>where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8, Global>where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq<Uuid> for Uuid

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl ReflectMessage for Uuid

fn descriptor(&self) -> MessageDescriptor

Gets a MessageDescriptor describing the type of this message.

fn transcode_to_dynamic(&self) -> DynamicMessagewhere Self: Sized,

Converts this message into an instance of DynamicMessage by going through the byte representation.
