Execute a change stream TVF query.

Fields

name: String

Name for this change stream.

start_time: Option<Timestamp>

Specifies that records with commit_timestamp greater than or equal to start_time should be returned.

end_time: Option<Timestamp>

Specifies that records with commit_timestamp less than or equal to end_time should be returned.

partition_token: Option<String>

Specifies which change stream partition to query, based on the content of child partitions records.

read_options: Vec<String>

Read options for this change stream query.

heartbeat_milliseconds: Option<i32>

Determines how frequently a heartbeat ChangeRecord will be returned in case there are no transactions committed in this partition, in milliseconds.

deadline_seconds: Option<i64>

Deadline for this change stream query, in seconds.

cloud_database_role: Option<String>

Database role to assume while performing this action. This should only be set for cloud requests. Setting the database role will enforce additional role-based access checks on this action.

Implementations

impl ExecuteChangeStreamQuery

pub fn partition_token(&self) -> &str

Returns the value of partition_token, or the default value if partition_token is unset.

pub fn heartbeat_milliseconds(&self) -> i32

Returns the value of heartbeat_milliseconds, or the default value if heartbeat_milliseconds is unset.

pub fn deadline_seconds(&self) -> i64

Returns the value of deadline_seconds, or the default value if deadline_seconds is unset.

pub fn cloud_database_role(&self) -> &str

Returns the value of cloud_database_role, or the default value if cloud_database_role is unset.

Trait Implementations

impl Clone for ExecuteChangeStreamQuery

fn clone(&self) -> ExecuteChangeStreamQuery

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExecuteChangeStreamQuery

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

Formats the value using the given formatter.

impl Default for ExecuteChangeStreamQuery

fn default() -> Self

Returns the “default value” for a type.

impl Message for ExecuteChangeStreamQuery

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

where 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( &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,

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

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

where Self: Sized,

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

impl PartialEq for ExecuteChangeStreamQuery

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