Test utilities for Persistent.

Required Methods

fn all(&self) -> Map<Val, Val>

Returns all data stored in persistent storage for the contract.

fn get_ttl<K: IntoVal<Env, Val>>(&self, key: &K) -> u32

Gets the TTL for the persistent storage entry corresponding to the provided key.

TTL is the number of ledgers left until the persistent entry is considered expired, excluding the current ledger.

Panics if there is no entry corresponding to the key, or if the entry has expired.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
