zstd-sys error

[MrBigtool]

Hi, I am new in rust but I want to do an experiment with this library in a web assembly project.

Just I am adding the lib:

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

[dependencies]
wasm-bindgen = "0.2.67"
datafusion = "7.0.0"
tokio = "1.17.0"
getrandom = { version = "0.2.5", features = ["js"] }`

And it is causing the error:

error: failed to run custom build command for 'zstd-sys v1.6.3+zstd.1.5.2'

I dont understand if I need to install ZSTD additionally in my mac to use this library.

You need zstd bindings for the target runtime, https://github.com/gyscos/zstd-rs/wiki/Compile-for-WASM

This may be related to dependencies brought in by parquet

I think this is complete now (the parquet support is optional and we are tracking remaining items in #7651)

FWIW zstd-rs does compile to wasm. You need to use the wasm and thin features: https://github.com/kylebarron/parquet-wasm/blob/24402e3719611b25662babb30f8f47181c0c2345/Cargo.toml#L89-L92
