Crate thisctx

A simple crate work with thiserror to create errors with contexts, inspired by snafu.

Example

use std::path::{Path, PathBuf};
use thisctx::WithContext;
use thiserror::Error;

#[derive(Debug, Error, WithContext)]
pub enum Error {
    #[error("I/O failed '{path}': {source}")]
    IoFaild {
        source: std::io::Error,
        path: PathBuf,
    },
}

fn load_config(path: &Path) -> Result<String, Error> {
    std::fs::read_to_string(path).context(IoFaildContext { path })
}
