In the following is an example expression using `buildGoModule`, the following arguments are of special significance to the function:
- `vendorHash`: is the hash of the output of the intermediate fetcher derivation. `vendorHash` can also take `null` as an input. When `null` is used as a value, rather than fetching the dependencies and vendoring them, we use the vendoring included within the source repo. If you'd like to not have to update this field on dependency changes, run `go mod vendor` in your source repo and set `vendorHash = null;`
- `vendorHash`: is the hash of the output of the intermediate fetcher derivation.
`vendorHash` can also be set to `null`.
In that case, rather than fetching the dependencies and vendoring them, the dependencies vendored in the source repo will be used.
To avoid updating this field when dependencies change, run `go mod vendor` in your source repo and set `vendorHash = null;`
To obtain the actual hash, set `vendorHash = lib.fakeSha256;` and run the build ([more details here](https://nixos.org/manual/nixpkgs/stable/#sec-source-hashes)).
- `proxyVendor`: Fetches (go mod download) and proxies the vendor directory. This is useful if your code depends on c code and go mod tidy does not include the needed sources to build or if any dependency has case-insensitive conflicts which will produce platform dependant `vendorHash` checksums.
