Struct InitRequest

pub struct InitRequest {
    pub path: String,
    pub producer_id: String,
    pub write_session_meta: HashMap<String, String>,
    pub get_last_seq_no: bool,
    pub partitioning: Option<Partitioning>,
}

Handshake request that must be sent to server first.

Fields

path: String

Full path of topic to write to.

producer_id: String

Producer identifier of client data stream. Used for message deduplication by sequence numbers.

write_session_meta: HashMap<String, String>

User metadata attached to this write session. Reader will get this session meta data with each message read.

get_last_seq_no: bool

Explicitly request for last sequential number It may be expensive, if producer wrote to many partitions before.

partitioning: Option<Partitioning>

Option for setting order on messages. If neither is set, no guarantees on ordering or partitions to write to.

Trait Implementations

impl Clone for InitRequest

fn clone(&self) -> InitRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InitRequest

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

Formats the value using the given formatter.

impl Default for InitRequest

fn default() -> Self

Returns the “default value” for a type.

impl Message for InitRequest

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>

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>

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 for InitRequest

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

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

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

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