cargo +nightly build --target=wasm32-unknown-unknown                                                                                  
warning: output filename collision.
The bin target `wasm-test` in package `wasm-test v1.0.0 (/Users/2075/dev/zero/interstellar/wasm-test)` has the same output filename as the lib target `wasm_test` in package `wasm-test v1.0.0 (/Users/2075/dev/zero/interstellar/wasm-test)`.
Colliding filename is: /Users/2075/dev/zero/interstellar/wasm-test/target/wasm32-unknown-unknown/debug/deps/wasm_test.wasm
The output filenames should be unique.
Consider changing their names to be unique or compiling them separately.
This may become a hard error in the future; see <https://github.com/rust-lang/cargo/issues/6313>.
If this looks unexpected, it may be a bug in Cargo. Please file a bug report at
https://github.com/rust-lang/cargo/issues/ with as much information as you
can provide.
