ebacktrace

Welcome to ebacktrace 🎉

This crate implements a simple error wrapper which captures a backtrace upon creation and can carry an optional textual description of the error.

Example

```rust use ebacktrace::define_error;

/// The error kind

[derive(Debug, Copy, Clone)]

enum ErrorKind { MyErrorA, Testolope }

// Define our custom error type define_error!(Error);

/// A function that will always fail fn will_fail() -> Result<(), Error> { Err(ErrorKind::Testolope)? }

// Will panic with a nice error if let Err(e) = will_fail() { eprintln!("Error: {:?}", e); panic!("Fatal error") } ```

Features

This crate currently has two feature gates: - derive_display (enabled by default): Use the Display-trait for Etrace<MyType> using the Debug representation of MyType (instead of the Display representation). This way you can pretty-print the underlying error types without the necessity to manually implement the Display-trait for them. - force_backtrace (disabled by default): If force_backtrace is enable, the backtrace is always captured, regardless whether RUST_BACKTRACE is set or not.
