Expand description

Owning dynamic type value. Value’s type is typically dictated by DuckDB (not by the caller).

See ValueRef for a non-owning dynamic type value.

Variants

`Null`

The value is a NULL value.

The value is a signed small integer.

`Int(i32)`

The value is a signed integer.

`BigInt(i64)`

The value is a signed big integer.

`HugeInt(i128)`
