error[E0277]: `main` has invalid return type `f32`
--> $DIR/termination-trait-test-wrong-type.rs:6:1
|
LL | #[test]
| ------- in this procedural macro expansion
LL | / fn can_parse_zero_as_f32() -> Result<f32, ParseFloatError> {
LL | | "0".parse()
LL | | }
| |_^ `main` can only return types that implement `Termination`
|
= help: the trait `Termination` is not implemented for `f32`
= note: required because of the requirements on the impl of `Termination` for `Result<f32, ParseFloatError>`
note: required by a bound in `assert_test_result`
--> $SRC_DIR/test/src/lib.rs:LL:COL

| ^^^^^^^^^^^ required by this bound in `assert_test_result`
= note: this error originates in the attribute macro `test` (in Nightly builds, run with -Z macro-backtrace for more info)
error: aborting due to previous error
