stdweb feature no longer builds?

[tangmi]

Hi, I noticed recently while working on winit that it no longer builds in the stdweb configuration due to this crate. Building instant directly yields (rustc 1.38.0 (625451e37 2019-09-23)):

PS D:\code\instant> cargo build --target wasm32-unknown-unknown --features stdweb

error: aborting due to 4 previous errors

Some errors have detailed explanations: E0425, E0433.
For more information about an error, try `rustc --explain E0425`.
error: Could not compile `instant`.

To learn more, run the command again with --verbose.

This was working in the past (sorry! I don't know exactly when!) and I noticed this in the last week or so. I'm pretty confident the stdweb and wasm-bindgen versions don't matter here, as I've tried older versions with the same results.

Adding an explicit dependency in instant's Cargo.toml to wasm-bindgen seems to solve the problem, but I'm mostly confused that (as far as I know) nothing changed to cause this break...?

Edit: I just realized I may have upgraded rust itself in between this working and not. Looking through the changelog, maybe rust-lang/cargo#6860 could cause a change here? But 1.36.0 was released in July and the last successful CI build for instant ran when 1.1.2 released earlier this month. 😕

Oh my goodness I'm such a doof, I wasn't building with cargo web. This is embarrassing.

Please ignore this issue!
