v0.11.4 compile error wasm target

[Saruniks]

I get compile error if trying to use reqwest v0.11.4. Build succeeds with reqwest v0.11.3.

error[E0277]: the trait bound Form: Clone is not satisfied
--> /home/test/.cargo/registry/src/github.com-1ecc6299db9ec823/reqwest-0.11.4/src/wasm/body.rs:24:15
|
24 | Multipart(Form),
| ^^^^ the trait Clone is not implemented for Form
|
= note: required by clone
= note: this error originates in a derive macro (in Nightly builds, run with -Z macro-backtrace for more info)

Cargo.toml

[dependencies.reqwest] version = "=0.11.4" default-features = true features = ["json", "multipart"]

Reproduced with rustc versions:
rustc 1.55.0-nightly (e6b4c252e 2021-06-25)
rustc 1.53.0 (53cb7b09b 2021-06-17)

Build command:
cargo build --target wasm32-unknown-unknown

Ah yikes, thanks for the report! It's probably this line that was recently added. We should remove that derive, and change that clone method to a try_clone that matches on the inner type.

Do you want to try to make a PR with that fix?
