Enum JsonWrapperBehavior 

pub enum JsonWrapperBehavior {
    Unspecified,
    Without,
    Unconditional,
    Conditional,
}

The SQL/JSON WRAPPER behaviour of JSON_QUERY (SQL:2016).

The optional ARRAY keyword and the UNCONDITIONAL default are semantically inert (PostgreSQL normalizes them away), so this closed enum folds WITH [UNCONDITIONAL] [ARRAY] WRAPPER onto Unconditional and WITHOUT [ARRAY] WRAPPER onto Without — the render re-parses to the same value.

Variants

Unspecified

No wrapper clause written.

Without

WITHOUT [ARRAY] WRAPPER.

Unconditional

WITH [UNCONDITIONAL] [ARRAY] WRAPPER.

Conditional

WITH CONDITIONAL [ARRAY] WRAPPER.
