Concrete Examples with Code, Config & Architecture

Example 1: [Use Case Name] - Embedded Configuration

Scenario: [Problem size, context, deployment target]

Architecture:

Application
HeliosDB Nano Client Library
In-Process SQLite/LSM Storage
[Optional: File System / Optional: Remote Sync]

Configuration (heliosdb.toml):

# HeliosDB Nano configuration for [feature]
[database]
path = "/path/to/data.db"
memory_limit_mb = 256
enable_wal = true
[feature]
enabled = true
mode = "[mode_name]"
[feature.settings]
param1 = "value1"
param2 = "value2"
max_connections = 10
timeout_ms = 5000
[monitoring]
metrics_enabled = false
verbose_logging = false

Implementation Code (Rust):

use heliosdb_nano::{Connection, Config};
#[tokio::main]
async fn main() -> Result<()> {
// Load configuration
let config = Config::from_file("heliosdb.toml")?;
// Initialize embedded database
let conn = Connection::open(config)?;
// Create table with feature-specific options
conn.execute(
"CREATE TABLE IF NOT EXISTS example_table (
id INTEGER PRIMARY KEY,
data TEXT NOT NULL,
created_at INTEGER DEFAULT (strftime('%s', 'now'))
)",
[],
)?;
// Insert data using feature
conn.execute(
"INSERT INTO example_table (data) VALUES (?1)",
[serde_json::json!({"key": "value"}).to_string()],
)?;
// Query demonstrating feature
let mut stmt = conn.prepare(
"SELECT id, data FROM example_table WHERE [feature_specific_clause]"
)?;
let results = stmt.query_map([], |row| {
Ok((row.get::<_, i32>(0)?, row.get::<_, String>(1)?))
})?;
for result in results {
let (id, data) = result?;
println!("ID: {}, Data: {}", id, data);
