Implementations

impl DynamoTable

pub fn hash_key_name(&self) -> &str

Get the hash key attribute name from the key schema.

pub fn range_key_name(&self) -> Option<&str>

Get the range key attribute name from the key schema (if any).

pub fn find_item_index( &self, key: &HashMap<String, AttributeValue>, ) -> Option<usize>

Find an item index by its primary key.

pub fn record_key_access(&mut self, key: &HashMap<String, AttributeValue>)

Record a partition key access for contributor insights. Only records if contributor insights is enabled.

pub fn record_item_access(&mut self, item: &HashMap<String, AttributeValue>)

Record a partition key access from a full item (extracts the key first).

pub fn top_contributors(&self, n: usize) -> Vec<(&str, u64)>

Get top N contributors sorted by access count (descending).

pub fn recalculate_stats(&mut self)

Recalculate item_count and size_bytes from the items vec.

Trait Implementations

fn clone(&self) -> DynamoTable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DynamoTable

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