.Rlib and .d file instead of .wasm

I want to compile a .rs file in a Rust lib to a .wasm.

RUSTFLAGS='-C link-arg=-s' cargo build --release --target wasm32-unknown-unknown

Instead of a .wasm file I get a .Rlib and .d file. What do I need to change to get a .wasm?

rustc considers .wasm files to fill the “native dynamic library” role in the WASM target. Add this to your Cargo.toml configuration to request that build instead of the default .rlib:

[lib]
crate-type = ["cdylib"]
