Struct Keys 

pub struct Keys { /* private fields */ }

Available on crate feature key-value only.

A streaming list of keys from a key-value store.

Keys are returned as a stream, allowing you to process them incrementally without loading the entire key set into memory. Use Keys::next() to retrieve keys one at a time, or Keys::collect() to gather all keys into a Vec.

After consuming the stream, you must check Keys::result() to determine whether the operation completed successfully.

Implementations

impl Keys

pub async fn next(&mut self) -> Option<String>

Gets the next key from the stream.

Returns None when there are no more keys available. You must await Keys::result() after the stream is exhausted to determine if all keys were read successfully.

pub async fn result(self) -> Result<(), Error>

Whether the key listing completed successfully or with an error.

This must be called after the stream has been fully consumed to check for errors that may have occurred during streaming.

pub async fn collect(self) -> Result<Vec<String>, Error>

Collects all keys into a Vec.

This is a convenience method for when the key set is small enough to fit in memory and you do not require streaming behaviour.

pub fn into_inner( self, ) -> (StreamReader<String>, FutureReader<Result<(), Error>>)

Extracts the underlying Wasm Component Model stream and future.
