The compiler says the trait Type<_> is not implemented for Vec although Vec<T: Type> is documented as a correct array type in the documentation
Versions affected
We are using sqlx 0.4 to be compatible with current stable actix_web runtime. It does not work with sqlx 0.5 neither.
Workaround
We have found a workaround: use Json<Vec<Occupation>> as a type and change the request accordingly: select name, to_jsonb(occupation) from speaker.
Discussion
It seems that Vec<T> has no implementation of trait Type when T is also Type.
If we were to add this implementation, would it solve the issue or is there something we haven't thought of? We are ready to contribute if our intuition is correct.

We encountered a problem with the inference of types with
sqlx
. We defined a custom enum for an array column and sqlx does not seem to like that.There is a small demo of this here.
