Struct qm_mongodb::options::TransactionOptions

#[non_exhaustive]
pub struct TransactionOptions {
    pub read_concern: Option<ReadConcern>,
    pub write_concern: Option<WriteConcern>,
    pub selection_criteria: Option<SelectionCriteria>,
    pub max_commit_time: Option<Duration>,
}

Contains the options that can be used for a transaction.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

read_concern: Option<ReadConcern>

The read concern to use for the transaction.

write_concern: Option<WriteConcern>

The write concern to use when committing or aborting a transaction.

selection_criteria: Option<SelectionCriteria>

The selection criteria to use for all read operations in a transaction.

max_commit_time: Option<Duration>

The maximum amount of time to allow a single commitTransaction to run.

Implementations

impl TransactionOptions

pub fn builder() -> TransactionOptionsBuilder<((), (), (), ())>

Create a builder for building TransactionOptions. On the builder, call .read_concern(...)(optional), .write_concern(...)(optional), .selection_criteria(...)(optional), .max_commit_time(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of TransactionOptions.
