Struct HostStorage 

pub struct HostStorage;

Storage backend that delegates to WASM host imports.

This is a zero-sized type that forwards all storage operations to the TruthLinked runtime via host function calls. Used when contracts execute on-chain.

Example

use truthlinked_sdk::backend::{HostStorage, StorageBackend};

let storage = HostStorage;
let value = storage.read_32(&slot)?;
