How to compile rusqlite 0.20.0 with cargo

Question

I'm trying to add sqlite support in my rust project. I found rusqlite on crates.io. I added the version line to Cargo.toml. I added some imports (unused) that I found on the rusqlite docs page. After running car go build I revived an error.

I hadn't implemented anything yet. I just wanted to get the dependency added and compiling. main.rs:

extern crate rusqlite;

use rusqlite::{Connection, Result};
use rusqlite::NO_PARAMS;

Cargo.toml:

[package]
name = "program"
version = "0.1.0"
authors = ["97"]

[dependencies]
argparse = "0.2.2"
rand = "0.4.0"
rusqlite = "0.20.0"

Error recived:

Edit

cargo 0.26.0 (41480f5cc 2018-02-26)

rustc 1.25.0 (84203cac6 2018-03-25)

Are you perhaps running an old version of Rust? Have you updated recently? Bound was added in 1.17.0 and RangeBounds in 1.28.0. — loganfsmyth
@loganfsmyth cargo --version [RET] cargo 0.26.0 (41480f5cc 2018-02-26) — 9716278
@loganfsmyth (Sorry. Forgot cargo and rustc are not the same.) rustc 1.25.0 (84203cac6 2018-03-25). It must be RangeBounds then. Do you know which version of rusqlite works with rust 1.25? — 9716278
I don't know, and there isn't guaranteed to be one. Would you be able to update? As you can see from that date, your version is more than a year and a half behind. — loganfsmyth
@loganfsmyth I could probably update. Just run rustup again, right? — 9716278

Most crates support only the latest Rust version. You could try to use an older version of the crate, but the easiest way is to update Rust to a currently-supported version.

If you're using Rust from a Linux distro, then uninstall it, and get it from https://rustup.rs which can keep it up to date. Rust ecosystem moves much faster than most distributions.

Run rustup update.
