Struct EowcPartitionProgress 

pub struct EowcPartitionProgress {
    pub last_output_key: Option<StateKey>,
    pub trigger: Option<WatermarkBound>,
}

Output progress of a partition in an EOWC over window whose windows may be closed by watermark, stored in the progress column of the intermediate_state_table.

Fields

last_output_key: Option<StateKey>

The key of the last output row. Absent when no row of the partition is retained.

trigger: Option<WatermarkBound>

The bound of the trigger registered in the watermark trigger table, which is not later than the watermark that closes the window of the next row to output.

impl Message for EowcPartitionProgress

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_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where 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(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

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

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

impl PartialEq for EowcPartitionProgress

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