How to use proconio?

I want to use proconio crate which is good for fast input in competitive programming . I am always encountering E0432 even I have added in toml file it's the crate name i.e proconio = "version" ,but still error is coming?

[package]
name = "atca"
version = "0.1.0"
authors = ["something"]
edition = "2018"

See more keys and their definitions at The Manifest Format - The Cargo Book

[dependencies]
proconio = "0.4.2"

Can you post a copy of your Cargo.toml and the code that’s producing the error? Without that, we can only speculate about what might be going wrong.

I added now how my Cargo.toml file is.Thanks.
