Exit on Error

Crates.io Documentation License

This crate provides utilities for exiting processes on errors gracefully, leveraging anyhow to display detailed error context and chained messages.

Examples

Exiting on error:

use anyhow::{Context, anyhow};
use eoe::ExitOnError;

Err::<(), _>(anyhow!("Mm-noom-ba-deh"))
    .context("Doom-boom-ba-beh")
    .context("Doo-boo-boom-ba-beh-beh")
    .exit_on_error();

Or if you prefer the word quit:

use anyhow::{Context, anyhow};
use eoe::QuitOnError;

Err::<(), _>(anyhow!("Mm-ba-ba-beh, mm-ba-ba-beh"))
    .context("Dee-day-da, ee-day-da")
    .quit_on_error();

The output style is customizable:

use eoe::{ExitOnError, Segment, Style};

let _ = eoe::ERROR.set(Segment {
    style: Style::new().bold().blue(),
    value: "Watchin' some good friends screamin'",
});
let _ = eoe::SEP.set(Segment {
    style: Style::new(),
    value: " 😱 ",
});
let _ = eoe::MESSAGE_STYLE.set(Style::new().italic().yellow());
let _ = eoe::MESSAGE_ON_NONE.set("Let me out");

None::<()>.exit_on_error();
