.wasm file contains personal information when decoded into wat

[cinqs]

Summary

I used wasm-bindgen (0.2.93) to convert my rust lib into wasm.
When installed with nodejs npm, and seen from the browser end, my personal information shown in the wat format

Additional Details

my rust code example:

#[wasm_bindgen]
pub fn bilateral_filter(
    img_data: &[u8],
    width: u32,
    height: u32,
    spatial_sigma: f32,
    range_sigma: f32,
    window_size: u32,
) -> Vec<u8>

This is a Rust issue and not a wasm-bindgen one.
There is a fair bit of information you can find here: rust-lang/rust#111540.

I hope this helps!
