Is it possible to use quote in no_std projects? #792 #264

hello! I want to use quote in my contract written in Ink! The problem is that I cannot compile it to WASM due to std usage. This is how I import quote:

quote = { version = "1.0", default-features = false }

I am trying to build a basic flipper example contract using this command: cargo contract build. Unfortunately, I got a lot of these kinds of errors:

error[E0152]: duplicate lang item in crate `core` (which `proc_macro2` depends on): `CStr`.

  = note: the lang item is first defined in crate `core` (which `std` depends on)
  = note: first definition in `core` loaded from /home/wojciech/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/wasm32-unknown-unknown/lib/libcore-4e48b611ead810f8.rlib

Here are a couple of things about using std in Ink!

fixed it by bumping quote version

quote = { version = "1.0.33", default-features = false }
