Using the C++ Implementation + +### 2.1 Basic Usage + +The C++ API is centered around `KvsBuilder` and `Kvs` classes. Here is a minimal example based on the test scenarios: + +```cpp +#include "kvsbuilder.hpp" +#include + +int main() { + // Use fully qualified names instead of 'using namespace' + auto open_res = score::mw::per::kvs::KvsBuilder(score::mw::per::kvs::InstanceId(0)) + .need_defaults_flag(true) + .need_kvs_flag(false) + .dir(".") + .build(); + if (!open_res) { + std::cerr << "Failed to open KVS: " << static_cast(open_res.error()) << std::endl; + return 1; + } + score::mw::per::kvs::Kvs kvs = std::move(open_res.value()); + + // Set a key-value pair + kvs.set_value("username", score::mw::per::kvs::KvsValue("alice")); + + // Read a value (will fall back to default if not set) + score::mw::per::kvs::Result get_res = kvs.get_value("username"); + if (get_res) { + std::cout << "username: " << get_res.value().as_string() << std::endl; + } + + // Read a default value (not set, but present in defaults) + auto get_default = kvs.get_value("language"); + if (get_default) { + std::cout << "language (default): " << get_default.value().as_string() << std::endl; + } + + // Check if a key exists (only if written) + if (kvs.key_exists("username").value_or(false)) { + std::cout << "username exists!" << std::endl; + } + + // Remove a key + kvs.remove_key("username"); + + // List all keys (only written keys, not defaults) + auto keys_res = kvs.get_all_keys(); + if (keys_res) { + std::cout << "All keys in KVS:" << std::endl; + for (const auto& key : keys_res.value()) { + std::cout << " " << key << std::endl; + } + } + + // Flush changes to disk + kvs.flush(); + + return 0; +} +``` + +## 3. Using the Rust Implementation + +### 3.1 Basic Usage + +From `examples/basic.rs`: +```rust +use rust_kvs::prelude::*; +use std::collections::HashMap; +use tempfile::tempdir; + +fn main() -> Result<(), ErrorCode> { + let dir = tempdir()?; + let dir_string = dir.path().to_string_lossy().to_string(); + let instance_id = InstanceId(0); + + // Build KVS instance + let builder = KvsBuilder::new(instance_id) + .dir(dir_string.clone()) + .kvs_load(KvsLoad::Optional); + let kvs = builder.build()?; + + // Set values + kvs.set_value("number", 123.0)?; + kvs.set_value("bool", true)?; + kvs.set_value("string", "First")?; + + // Get value + let value = kvs.get_value("number")?; + println!("number = {:?}", value); + + Ok(()) +} +``` + +### 3.2 Snapshots Example + +From `examples/snapshots.rs`: +```rust +let max_count = kvs.snapshot_max_count() as u32; +for index in 0..max_count { + kvs.set_value("counter", index)?; + kvs.flush()?; + println!("Snapshot count: {:?}", kvs.snapshot_count()); +} + +// Restore a snapshot +kvs.snapshot_restore(SnapshotId(2))?; +``` + +### 3.3 Defaults Example + +From `examples/defaults.rs`: +```rust +// Create defaults file and build KVS instance with defaults +create_defaults_file(dir.path().to_path_buf(), instance_id)?; +let builder = KvsBuilder::new(instance_id) + .dir(dir_string) + .defaults(KvsDefaults::Required); +let kvs = builder.build()?; + +// Get default value +let k1_value = kvs.get_default_value("k1")?; +println!("k1 = {:?}", k1_value); +``` +## 4. Default value file example +This file should be placed in the working directory: +```json +{ + "language": "en", + "theme": "dark", + "timeout": 30 +} +``` + +**Important:** +- If you open the KVS with `.need_defaults_flag(true)`, the file must exist. +- The KVS will use these defaults for any key not explicitly set. +- You must also provide a CRC file (e.g., `defaults.json.crc`) alongside the defaults file. This CRC file is generated using the Adler-32 checksum algorithm, as implemented in the codebase. The CRC ensures the integrity of the defaults file at runtime. +## 5. More Examples +- See `src/cpp/tests/` for C++ test scenarios and usage patterns. +- See `src/rust/rust_kvs/examples/` for Rust usage patterns. diff --git a/src/cpp/src/internal/error.cpp
