Struct PartitionStartRecord 

#[non_exhaustive]
pub struct PartitionStartRecord {
    pub start_timestamp: Option<Timestamp>,
    pub record_sequence: String,
    pub partition_tokens: Vec<String>,
    /* private fields */
}

A partition start record serves as a notification that the client should schedule the partitions to be queried. PartitionStartRecord returns information about one or more partitions.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

start_timestamp: Option<Timestamp>

Start timestamp at which the partitions should be queried to return change stream records with timestamps >= start_timestamp. DataChangeRecord.commit_timestamps, PartitionStartRecord.start_timestamps, PartitionEventRecord.commit_timestamps, and PartitionEndRecord.end_timestamps can have the same value in the same partition.

record_sequence: String

Record sequence numbers are unique and monotonically increasing (but not necessarily contiguous) for a specific timestamp across record types in the same partition. To guarantee ordered processing, the reader should process records (of potentially different types) in record_sequence order for a specific timestamp in the same partition.

partition_tokens: Vec<String>

Unique partition identifiers to be used in queries.

Implementations

impl PartitionStartRecord

pub fn new() -> Self

Creates a new default instance.

pub fn set_start_timestamp<T>(self, v: T) -> Self

where T: Into<Timestamp>,

Sets the value of start_timestamp.

pub fn set_or_clear_start_timestamp<T>(self, v: Option<T>) -> Self

where T: Into<Timestamp>,

Sets or clears the value of start_timestamp.

pub fn set_record_sequence<T: Into<String>>(self, v: T) -> Self

Sets the value of record_sequence.

pub fn set_partition_tokens<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<String>,

Sets the value of partition_tokens.

Trait Implementations

impl Clone for PartitionStartRecord

fn clone(&self) -> PartitionStartRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionStartRecord

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

Formats the value using the given formatter.

impl Default for PartitionStartRecord

fn default() -> PartitionStartRecord

Returns the “default value” for a type.

impl Message for PartitionStartRecord

fn typename() -> &'static str

The typename of this message.

impl PartialEq for PartitionStartRecord

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