pub fn concat(
lhs: &Value<'_>,
rhs: &Value<'_>,
) -> Result<Value<'static>, EvalError>Expand description
json_build_object(k, v, k, v, …) — variadic, even-length.
NULL key → error (PG: “argument cannot be null”). Values encoded
via value_to_json_text. Returns Value::Json.
v7.37.17 (17.6 siblings) — jsonb_concat(a, b) — function form
of the || operator. Object + object merges keys (right wins on
duplicates); array + array appends; array + scalar appends the
scalar; scalar + scalar makes a 2-element array (PG semantics).
