How do I map JSONB[] to a Vec of custom types

[finlaydotb]

I have a database with a column defined as

  ---
   data JSONB[] NOT NULL,
  .... 

I have a struct with this shape

struct Content {
-- other fields
data: Vec<Data>
}

where Data is another struct.

In my select query I keep getting

|_________^ expected `Vec<Data>`, found `Vec<Value>`

Problem is that it seems the mapping expects the data type on the struct to be of type Vec<Value> but I need it to be of Vec<Data>.

Any ideas how to fix this?
