https://github.com/pantsbuild/pants/pull/16843 attempts to add a

GoBuildContext

type which will hold compiler options to apply when compiling Go files. The goal is to use the multi-Parameter syntax of

Get

to allow the

go_binary

rule to override

GoBuildContext

with binary-specific options.

As documented in that PR, I get lots of rule graph errors instead. (The initial option was a "cgo allowed" option which could disable cgo usage for a binary through all of its transitive dependencies.)

So many rule graph errors that I don't know where to begin to diagnose what missing. I attempted to see if the

in_scope_types

parameter of

@union

was involved, but did not manage to solve the rule graph errors.

any advice?
