This example deletes the key mykey from the namespace test in the set myset:

let key = as_key!("test", "test", "mykey");
match client.delete(&WritePolicy::default(), &key).await {
    Ok(true) => println!("Record deleted"),
    Ok(false) => println!("Record did not exist"),
    Err(err) => println!("Error deleting record: {}", err),
};

📖 API reference: Client::delete | WritePolicy::default

Delete every record in a set

To delete all the records in a set with a single server-side call, use Client::truncate. Unlike Client::delete, it takes an AdminPolicy, and it takes the namespace and set name instead of a key. The last argument is a cutoff time in nanoseconds since the Unix epoch. 0 deletes every record in the set:

use aerospike::AdminPolicy;


client.truncate(&AdminPolicy::default(), "test", "myset", 0).await?;

📖 API reference: Client::truncate | AdminPolicy

truncate returns Result<()>. It doesn’t return a count of the records it deleted.

To delete only the records that were last updated before a given time, pass that time as the last argument. Records updated at or after the cutoff stay:

use std::time::{SystemTime, UNIX_EPOCH};


let cutoff = SystemTime::now().duration_since(UNIX_EPOCH)
    .expect("system clock is before the Unix epoch")
    .as_nanos() as i64;
client.truncate(&AdminPolicy::default(), "test", "myset", cutoff).await?;
