Struct PostArchiverManager 

pub struct PostArchiverManager<C = Connection> {
    pub caches: Arc<Mutex<ManagerCaches>>,
    pub path: PathBuf,
    /* private fields */
}

Available on crate feature utils only.

Core manager type for post archive operations with SQLite backend

Provides database connection management and access to entity operations through the Binded type via bind().

Examples

use post_archiver::manager::PostArchiverManager;

let manager = PostArchiverManager::open_or_create("./data").unwrap();

Fields

caches: Arc<Mutex<ManagerCaches>>

path: PathBuf

Implementations

impl PostArchiverManager

pub fn create<P>(path: P) -> Result<Self>

where P: AsRef<Path>,

Creates a new archive at the specified path

Panics

Panics if the path already contains a database file.

Examples

use post_archiver::manager::PostArchiverManager;

let manager = PostArchiverManager::create("./new_archive").unwrap();

pub fn open<P>(path: P) -> Result<Option<Self>>

where P: AsRef<Path>,

Opens an existing archive at the specified path

Returns

• Ok(Some(manager)) if archive exists and version is compatible
• Ok(None) if archive doesn’t exist
• Err(_) on database errors

Examples

use post_archiver::manager::PostArchiverManager;

if let Some(manager) = PostArchiverManager::open("./archive").unwrap() {
    println!("Archive opened successfully");
}

pub fn open_uncheck<P>(path: P) -> Result<Option<Self>>

where P: AsRef<Path>,

Opens an existing archive at the specified path without checking version.

Returns

• Ok(Some(manager)) if archive exists
• Ok(None) if archive doesn’t exist
• Err(_) on database errors

pub fn open_or_create<P>(path: P) -> Result<Self>

where P: AsRef<Path>,

Examples

use post_archiver::manager::PostArchiverManager;

let manager = PostArchiverManager::open_or_create("./archive").unwrap();

pub fn open_in_memory() -> Result<Self>

Creates an in-memory database

Examples

use post_archiver::manager::PostArchiverManager;

let manager = PostArchiverManager::open_in_memory().unwrap();

pub fn transaction(&mut self) -> Result<PostArchiverManager<Transaction<'_>>>

Starts a new transaction

Examples

use post_archiver::manager::PostArchiverManager;

let mut tx = manager.transaction().unwrap();
// ... perform operations
tx.commit().unwrap();

pub fn bind<Id: BindableId>(&self, id: Id) -> Binded<'_, Id, C>

The type parameter is inferred from the ID argument — no turbofish needed.

Examples

let binded = manager.bind(post_id);
// binded is Binded<'_, PostId>
