remove support for returning vectors for the time being

 ## Returning vectors
 
-There is a mandatory extra step to returning vectors -- you need to `log` every element before returning the vector.
-
-You must not mix any unrelated `log`s once you start logging vector elements. 
-
-These logs must be the last ones you make.
-
-
-### A simple case:
-```rust,ignore
-{{#include ../../../packages/fuels/tests/test_projects/vectors/src/main.sw:sway_returning_a_vec}}
-```
-
-Calling it from the SDK would look like this:
-
-```rust,ignore
-{{#include ../../../packages/fuels/tests/harness.rs:harness_returning_a_vec}}
-```
-
-### Respect the order
-
-If you have vectors embedded in some other type, you must take care to log them in order:
-
-```rust,ignore
-{{#include ../../../packages/fuels/tests/test_projects/vectors/src/data_structures.sw:sway_nested_vec_types}}
-```
-
-you must take care to log them in order:
-```rust,ignore
-{{#include ../../../packages/fuels/tests/test_projects/vectors/src/main.sw:sway_returning_type_w_nested_vectors}}
-```
-
-where `log_vec` is a helper defined as:
-```rust,ignore
-{{#include ../../../packages/fuels/tests/test_projects/vectors/src/utils.sw:sway_log_vec_helper}}
-```
-
-
-Calling it from the SDK would look like this:
-
-```rust,ignore
-{{#include ../../../packages/fuels/tests/harness.rs:harness_returning_type_w_nested_vectors}}
-```
-
-
-### Nested vectors
-
-There is one more step you must take if you're logging a vector nested immediately inside another vector -- e.g. `Vec<Vec<u32>>`
-
-An example:
-
-```rust,ignore
-{{#include ../../../packages/fuels/tests/test_projects/vectors/src/main.sw:sway_returning_immediately_nested_vectors}}
-```
-Calling it from the SDK would look like this:
-
-```rust,ignore
-{{#include ../../../packages/fuels/tests/harness.rs:harness_returning_immediately_nested_vectors}}
-```
-
-
-To log a `Vec<Vec<u32>>` we need to do the following:
-
-1. We're looking at the parent vector. The type is `Vec<Vec<..>>`.
-
-    This is a vector with two elements `inner_vec_1` and `inner_vec_2`. Both are vectors themselves.
-
-2. We're looking at `inner_vec_1`. The type is `Vec<u32>`.
-
-    This is a vector with one element: `1`. Log it.
-
-3. We're looking at the second element of the parent vector `inner_vec_2`. The type is `Vec<u32>`.
-
-   This is a vector with one element: `2`. Log it.
-
-We've finished logging the elements of the parent vector. Since the type is `Vec<Vec<..>>` we have an additional step.
-
-4. Call `log` on each element of the vector:
-
-   `log(inner_vec_1)`
-
-   `log(inner_vec_2)`
-
-   In the example this is done by the `log_vec` helper.
+This is currently not supported. If you try returning a type that is or contains a vector you will get a compile time error.
