[rust] Add use declarations to Rust-generated bindings for imported FB definitions (#5645) * Bugfix for Rust generation of union fields named with language keywords Looking at ParseField, it appears that in the case of unions, an extra field with a `UnionTypeFieldSuffix` is added to the type definition, however, if the name of this field is a keyword in the target language, it isn't escaped. For example, if generating code for rust for a union field named `type`, flatc will generate a (non-keyword escaped) field named `type_type` for this hidden union field, and one (keyword escaped) called `type_` for the actual union contents. When the union accessors are generated, they refer to this `type_type` field, but they will escape it mistakenly, generating code like this: ``` #[inline] #[allow(non_snake_case)] pub fn type__as_int(&self) -> Option<Int<'a>> { if self.type__type() == Type::Int { self.type_().map(|u| Int::init_from_table(u)) } else { None } } ``` Which will fail to build because the field is called `self.type_type()`, not `self.type__type()`. * [Rust] Add crate-relative use statements for FBS includes. At present if a flatbuffer description includes a reference to a type in another file, the generated Rust code needs to be hand-modified to add the appropriate `use` statements. This assumes that the dependencies are built into the same crate, which I think is a reasonable assumption? * Revert "[Rust] Add crate-relative use statements for FBS includes." This reverts commit d554d79fecf5afd6da6fb993b30b4cd523a5889a. * Add updated generated test files. * Fixing Rust test harness to handle new includes. Test binaries need to add references to generated code that's transitively included. This also has the knock-on in that this code (which is referenced by include directives directly in the flatbuffer schema files) also needs to be generated, hence the changes to generate_code.sh. * Test harnesses expect test data to be checked in. Put include_test2 files into the same directory as the include_test2 schema definition. Update all code generation scripts (forgot the batch file from last time). Path updates in Rust test. * Include updated generated code * Address comments raised in PR * Fix failing Rust tests. * Previous merge clobbered this branch change. * Add updated imports to benchmarks. * Clarifying comment per PR request * Update documentation comments per feedback * Remove non-Rust generated files for include tests, per feedback from @rw/@aardappel * Broken code generation batch file * Fix typo * Add TODO for tidying up use declaration traversal sometime in the future * Update test files.
