Struct EventToken

pub struct EventToken {
    pub timestamp: i64,
    pub shard: String,
    pub position: String,
}

EventToken is a structure that describes a point in time in a replication stream on one shard. The most recent known replication position can be retrieved from vttablet when executing a query. It is also sent with the replication streams from the binlog service.

Fields

timestamp: i64

timestamp is the MySQL timestamp of the statements. Seconds since Epoch.

shard: String

The shard name that applied the statements. Note this is not set when streaming from a vttablet. It is only used on the client -> vtgate link.

position: String

The position on the replication stream after this statement was applied. It is not the transaction ID / GTID, but the position / GTIDSet.

Trait Implementations

impl Clone for EventToken

fn clone(&self) -> EventToken

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EventToken

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

Formats the value using the given formatter.

impl Default for EventToken

fn default() -> Self

Returns the “default value” for a type.

impl Message for EventToken

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 EventToken

fn eq(&self, other: &EventToken) -> 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.
