String with escaping char dump error

[CXWorks]

Hi,

Thanks for your time and patience. I'm not sure if it's bug in the lab or the inconsistency in my toml file, I need your help, thanks.

I'm using your library to parse Rust's project configuration file, Cargo.toml, in some projects, I will have following sections:

[target."cfg(all(target_arch = \"wasm32\", not(any(target_os = \"emscripten\", target_os = \"wasi\"))))".dependencies.wasm-bindgen]
version = "0.2"
optional = true

There are escaping symbols for the " chars, if I load the file into your library and dump the result, it will be like:

[target."cfg(all(target_arch = \\\"wasm32\\\", not(any(target_os = \\\"emscripten\\\", target_os = \\\"wasi\\\"))))".dependencies.wasm-bindgen]
version = "0.2"
optional = true

The extra \\ will be added for all the escaping locations, can you help me with this issue?
