Struct IndentedSection

pub struct IndentedSection<H, B> { /* private fields */ }

An indented section with a header for an error report

Details

This helper provides two functions to help with constructing nicely formatted error reports. First, it handles indentation of every line of the body for you, and makes sure it is consistent with the rest of color-eyre’s output. Second, it omits outputting the header if the body itself is empty, preventing unnecessary pollution of the report for sections with dynamic content.

Examples

use color_eyre::{eyre::eyre, SectionExt, Section, eyre::Report};
use std::process::Command;
use tracing::instrument;

trait Output {
    fn output2(&mut self) -> Result<String, Report>;
}

impl Output for Command {
    #[instrument]
    fn output2(&mut self) -> Result<String, Report> {
        let output = self.output()?;

        let stdout = String::from_utf8_lossy(&output.stdout);

        if !output.status.success() {
            let stderr = String::from_utf8_lossy(&output.stderr);
            Err(eyre!("cmd exited with non-zero status code"))
                .with_section(move || stdout.trim().to_string().header("Stdout:"))
                .with_section(move || stderr.trim().to_string().header("Stderr:"))
        } else {
            Ok(stdout.into())
        }
    }
}
