Enum ReadConcernLevel

#[non_exhaustive]pub enum ReadConcernLevel {
    Local,
    Majority,
    Linearizable,
    Available,
    Snapshot,
    Custom(String),
}

Expand description

Specifies the level consistency and isolation properties of a given ReadCocnern.

See the documentation here for more information about read concerns.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Local

See the specific documentation for this read concern level here.

Majority

See the specific documentation for this read concern level here.

Linearizable

See the specific documentation for this read concern level here.

Available

See the specific documentation for this read concern level here.

Snapshot

See the specific documentation for this read concern level here.

Custom(String)

Specify a custom read concern level. This is present to provide forwards compatibility with any future read concerns which may be added to new versions of MongoDB.
