Function export_database_with_options 

pub async fn export_database_with_options(
    storage: &mut BlockStorage,
    options: ExportOptions,
) -> Result<Vec<u8>, DatabaseError>

Export database with advanced options (streaming, progress callbacks)

For large databases (>100MB), this function processes blocks in chunks, yields to the event loop between chunks, and reports progress.

Arguments

• storage - Block storage containing the database
• options - Export configuration (size limits, chunk size, progress callback)

Returns

Complete database as bytes

Example

use absurder_sql::storage::export::{export_database_with_options, ExportOptions};
use absurder_sql::storage::BlockStorage;

async fn export_with_progress(mut storage: BlockStorage) -> Result<Vec<u8>, absurder_sql::types::DatabaseError> {
    let options = ExportOptions {
        max_size_bytes: Some(1024 * 1024 * 1024), // 1GB limit
        chunk_size_bytes: Some(10 * 1024 * 1024), // 10MB chunks
        progress_callback: Some(Box::new(|exported, total| {
            println!("Progress: {}/{} bytes ({:.1}%)", 
                exported, total, (exported as f64 / total as f64) * 100.0);
        })),
    };
    export_database_with_options(&mut storage, options).await
