Struct Precondition

pub struct Precondition {
    pub exists: Option<bool>,
    pub update_time: Option<DateTime<Utc>>,
}

A precondition on a document, used for conditional operations.

This type is not used in any activity, and only used as part of another schema.

Fields

exists: Option<bool>

When set to true, the target document must exist. When set to false, the target document must not exist.

update_time: Option<DateTime<Utc>>

When set, the target document must exist and have been last updated at that time. Timestamp must be microsecond aligned.
