Enum LevelKeys 

pub enum LevelKeys {
    Whole,
    Without(Vec<String>),
    Only {
        kept: Vec<String>,
        masked: Vec<String>,
    },
}

Which keys of a stored document a composed level returns.

Variants

Whole

The whole document. The root’s shape: it is projected afterwards exactly as a flat read of the same query is, so it reads what a flat read reads.

Without(Vec<String>)

The whole document, less these keys.

The root’s shape when some of its stored keys are embedded in their own place: the embedded value is the gated one, and the stored one — which the level’s predicate never filtered — does not leave the database.

Only

Only these keys, and these keys as null.

An embedded level’s shape. A key the caller may not see never leaves the database: masked keys are written as SQL NULL, and a key in neither list is not returned at all.

Fields

kept: Vec<String>

Stored keys returned with their values, when the document has them.

masked: Vec<String>

Stored keys returned as null whatever the document holds.
