# First Welcome Library Crate
this is a demo rust library published on crates.io
to use this library you have to add following line in dependency section of cargo.toml
`library_crate = "0.1.2"`
your cargo.toml file should look like this:
```
[package]
name = "library_crate"
version = "0.1.2"
authors = ["SyedHussainAhmed121 <shas_virgo121@yahoo.com>"]
edition = "2018"
[dependencies]
library_crate = "0.1.2"
```
In `src/main.rs` you can use like this:
```
use library_crate;
fn main() {
println!("Hello, world!");
library_crate::welcome();
}
```
following will also work:
```
use library_crate::welcome;
fn main() {
println!("Hello, world!");
welcome();
}
```
now `cargo run` for results
