Struct StartSession 

Source 
pub struct StartSession<'a> { /* private fields */ }
Expand description

Starts a new ClientSession. Construct with Client::start_session.

Implementations§

Source§

impl StartSession<'_>

Source

pub fn with_options(self, value: impl Into<Option<SessionOptions>>) -> Self

Set all options. Note that this will replace all previous values set.

Source

pub fn default_transaction_options(self, value: TransactionOptions) -> Self

The default options to use for transactions started on this session.

If these options are not specified, they will be inherited from the Client associated with this session. They will not be inherited from the options specified on the Database or Collection associated with the operations within the transaction.

Source

pub fn causal_consistency(self, value: bool) -> Self

If true, all operations performed in the context of this session will be causally consistent.

Defaults to true if SessionOptions::snapshot is unspecified.

Source

pub fn snapshot(self, value: bool) -> Self

If true, all read operations performed using this client session will share the same snapshot. Defaults to false.

Source

pub fn snapshot_time(self, value: Timestamp) -> Self

The snapshot time to use for a snapshot session. This option can only be set if snapshot is set to true.

Source§

impl<'a> StartSession<'a>

Source

pub fn run(self) -> Result<ClientSession>

Available on crate feature sync only.

Synchronously execute this action.
