Struct polodb_core::Database
source · pub struct Database { /* private fields */ }
Expand description
API wrapper for Rust-level
Use Database::open_file
API to open a database. A main database file will be
generated in the path user provided.
When you own an instance of a Database, the instance holds a file descriptor of the database file. When the Database instance is dropped, the handle of the file will be released.
Collection
A Collection
is a dataset of a kind of data.
You can use Database::create_collection
to create a data collection.
To obtain an exist collection, use Database::collection
,
Implementations§
source§impl Database
impl Database
pub fn set_log(v: bool)
sourcepub fn get_version() -> String
pub fn get_version() -> String
Return the version of package version in string.
Defined in Cargo.toml
.
pub fn open_memory() -> DbResult<Database>
pub fn open_memory_with_config(config: Config) -> DbResult<Database>
pub fn open_file<P: AsRef<Path>>(path: P) -> DbResult<Database>
pub fn open_file_with_config<P: AsRef<Path>>( path: P, config: Config ) -> DbResult<Database>
sourcepub fn create_collection(&self, name: &str) -> DbResult<()>
pub fn create_collection(&self, name: &str) -> DbResult<()>
Creates a new collection in the database with the given name
.
sourcepub fn create_collection_with_session(
&self,
name: &str,
session: &mut ClientSession
) -> DbResult<()>
pub fn create_collection_with_session( &self, name: &str, session: &mut ClientSession ) -> DbResult<()>
Creates a new collection in the database with the given name
.
sourcepub fn collection<T: Serialize>(&self, col_name: &str) -> Collection<T>
pub fn collection<T: Serialize>(&self, col_name: &str) -> Collection<T>
Return an exist collection. If the collection is not exists, a new collection will be created.
pub fn start_session(&self) -> DbResult<ClientSession>
sourcepub fn list_collection_names(&self) -> DbResult<Vec<String>>
pub fn list_collection_names(&self) -> DbResult<Vec<String>>
Gets the names of the collections in the database.
sourcepub fn list_collection_names_with_session(
&self,
session: &mut ClientSession
) -> DbResult<Vec<String>>
pub fn list_collection_names_with_session( &self, session: &mut ClientSession ) -> DbResult<Vec<String>>
Gets the names of the collections in the database.
