Struct StreamRecord

pub struct StreamRecord {
    pub approximate_creation_date_time: Option<f64>,
    pub keys: Option<HashMap<String, AttributeValue>>,
    pub new_image: Option<HashMap<String, AttributeValue>>,

}

A description of a single data modification that was performed on an item in a DynamoDB table.

Fields

approximate_creation_date_time: Option<f64>

The approximate date and time when the stream record was created, in UNIX epoch time format.

keys: Option<HashMap<String, AttributeValue>>

The primary key attribute(s) for the DynamoDB item that was modified.

new_image: Option<HashMap<String, AttributeValue>>

The item in the DynamoDB table as it appeared after it was modified.

old_image: Option<HashMap<String, AttributeValue>>

The item in the DynamoDB table as it appeared before it was modified.

sequence_number: Option<String>

The sequence number of the stream record.

size_bytes: Option<i64>

The size of the stream record, in bytes.

stream_view_type: Option<String>

The type of data from the modified DynamoDB item that was captured in this stream record:

• KEYSONLY - only the key attributes of the modified item.

• NEWIMAGE - the entire item, as it appeared after it was modified.

• OLDIMAGE - the entire item, as it appeared before it was modified.

• NEWANDOLDIMAGES - both the new and the old item images of the item.

Trait Implementations

impl Clone for StreamRecord

fn clone(&self) -> StreamRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamRecord

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

Formats the value using the given formatter.

impl Default for StreamRecord

fn default() -> StreamRecord

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StreamRecord

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StreamRecord

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