Failed to build 0.2.7

[kafji]

I can't build crates that depend on http version 0.2.7.

$ cargo clean && cargo build -v -j1

error: could not compile `http` due to 2 previous errors

The errors references the Extension::check function:

            .and_then(|boxed| (&**boxed as &(dyn Any + 'static)).downcast_ref())
    }

    pub fn check(&self, type_id:&TypeId) -> bool {
        self.map.contains(type_id)
    }

    /// Get a mutable reference to a type previously inserted on this `Extensions`.

What's weird, is that I can't find that function in the trunk, neither in HEAD nor in v0.2.7.

That function has not existed. Do you have a vendored and modified version? Or are using a Cargo patch or replace?

[kafji]

@seanmonstar No.

Maybe some .cargo/config file thing? You can see the source of the crate published doesn't contain the method either: https://docs.rs/http/0.2.7/src/http/extensions.rs.html

[kafji]

Nothing exceptional in my cargo config file.

$ cat ~/.cargo/config.toml 
# https://raw.githubusercontent.com/bevyengine/bevy/master/.cargo/config_fast_builds

[target.x86_64-unknown-linux-gnu]

[target.x86_64-pc-windows-msvc]

Yeah. I tried building it in different machine and it works. The problem is localized to my machine. Maybe cargo bug. I'll try nuking its cache later.

Thanks for the help and thank you for maintaining this crate.
