This repo contains tests that exercise passing flatbuffers between Go and Rust.
A simple flatbuffers schema for an expression tree is contained in tree.fbs.
Generated code produced by flatc --rust is in ./rust/expr_tree/src/tree_generated.rs.
The Go counterpart is in ./tree/*.go.
Go code in evaluation can build simple expression trees as flatbuffers and evaluate
them.
Likewise, Rust code in rust/expr_tree/src/lib.rs does the same.
To build:
cd rust/expr_tree
cargo build --lib --release
cd -
go test ./...
Relevant tests are in ./evaluation/rust_eval_test.go.
