Struct BackendMigration 

pub struct BackendMigration;

Migration utilities for moving data between backends

Implementations

impl BackendMigration

pub fn migrate( _source: &dyn VectorBackend, _dest: &mut dyn VectorBackend, ) -> Result<MigrationStats>

Migrate all data from source to destination backend

pub fn migrate_cids( source: &dyn VectorBackend, dest: &mut dyn VectorBackend, cids: &[Cid], ) -> Result<MigrationStats>

Migrate specific CIDs from source to destination

pub fn migrate_cids_with_progress<F>( source: &dyn VectorBackend, dest: &mut dyn VectorBackend, cids: &[Cid], progress_callback: F, ) -> Result<MigrationStats>

where F: FnMut(usize, usize),

Migrate specific CIDs with progress tracking

The progress callback receives (current_index, total_count) for each processed CID

Example

use ipfrs_semantic::adapters::BackendMigration;

let stats = BackendMigration::migrate_cids_with_progress(
    &source,
    &mut dest,
    &cids,
    |current, total| {
        println!("Progress: {}/{} ({:.1}%)", current, total, (current as f64 / total as f64) * 100.0);
    }
)?;

pub fn export_to_json( backend: &dyn VectorBackend, cids: &[Cid], ) -> Result<String>

Export vectors to a portable format

pub fn import_from_json( backend: &mut dyn VectorBackend, json: &str, ) -> Result<usize>

Import vectors from JSON
