error[E0432]: unresolved import `simplelog::TestLogger`

[blaine-dodson]

Can anyone else reproduce this error, or is it just me? I create a new cargo project

Cargo.toml

[package]
name = "testing"
version = "0.1.0"
authors = ["Ammon Dodson <github@adodson.e4ward.com>"]
edition = "2018"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
simplelog = "0.8"

main.rs

use simplelog::TestLogger;

fn main() {
    println!("Hello, world!");
}

Terminal:

If you wanna use the TestLogger (which is only useful for actual tests), you need to enable the "test" feature of simplelog. You Cargo.toml entry needs to look like this: simplelog = { version = "0.8", features = ["test"] }

That did it. Thank you very much.
