Errors when targeting webassembly
I get the following errors when targeting wasm32-unknown-unknown.
Am I doing something wrong or is wasm not supported, yet?
$ cargo build --lib --target wasm32-unknown-unknown
Compiling secp256k1-sys v0.4.0
Compiling js-sys v0.3.47
Compiling exonum_libsodium-sys v0.0.23
