Struct mongodb::Client [−][src]
pub struct Client { /* fields omitted */ }
Expand description
This is the main entry point for the API. A Client
is used to connect to a MongoDB cluster.
By default, it will monitor the topology of the cluster, keeping track of any changes, such
as servers being added or removed.
Client
uses std::sync::Arc
internally,
so it can safely be shared across threads or async tasks. For example:
let client = Client::with_uri_str("mongodb://example.com").await?; for i in 0..5 { let client_ref = client.clone(); task::spawn(async move { let collection = client_ref.database("items").collection(&format!("coll{}", i)); // Do something with the collection }); }
TCP Keepalive
TCP keepalive is enabled by default with tcp_keepalive_time
set to 120 seconds. The
driver does not set tcp_keepalive_intvl
. See the
MongoDB Diagnostics FAQ keepalive section
for instructions on setting these values at the system level.
Implementations
Creates a new Client
connected to the cluster specified by uri
. uri
must be a valid
MongoDB connection string.
See the documentation on
ClientOptions::parse
for more details.
Creates a new Client
connected to the cluster specified by options
.
Gets the default selection criteria the Client
uses for operations..
Gets the default read concern the Client
uses for operations.
Gets the default write concern the Client
uses for operations.
Gets a handle to a database specified by name
in the cluster the Client
is connected to.
The Database
options (e.g. read preference and write concern) will default to those of the
Client
.
This method does not send or receive anything across the wire to the database, so it can be used repeatedly without incurring any costs from I/O.
Gets a handle to a database specified by name
in the cluster the Client
is connected to.
Operations done with this Database
will use the options specified by options
by default
and will otherwise default to those of the Client
.
This method does not send or receive anything across the wire to the database, so it can be used repeatedly without incurring any costs from I/O.
Gets information about each database present in the cluster the Client is connected to.
