Crate thisctx

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

Examples

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

thisctx! {
	#[derive(Debug, Error)]
	pub enum Error {
		#[error("I/O failed '{}': {src}", .ctx.0.display())]
		IoFaild {
			#[source]
			@source
			src: std::io::Error,
			@context
			ctx:
				#[derive(Debug)]
				struct (PathBuf),
		},
   }
}

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