Module kv 

Key-value storage for plugin state.

Provides persistent storage that survives across plugin invocations.

Example

use zlayer_sdk::kv;

// Store a value
kv::set("state", "counter", b"42")?;

// Retrieve a value
if let Some(data) = kv::get("state", "counter")? {
    let count: i32 = core::str::from_utf8(&data)
        .ok()
        .and_then(|s| s.parse().ok())
        .unwrap_or(0);
}

// String convenience methods
kv::set_string("state", "name", "my-value")?;
let name = kv::get_string("state", "name")?;
