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.
```rust use ebacktrace::define_error; use std::fmt::{ self, Display, Formatter };
/// The error kind
enum ErrorKind { MyErrorA, Testolope } impl Display for ErrorKind { fn fmt(&self, f: &mut Formatter) -> fmt::Result { write!(f, "{:#?}", self) } } // Define our custom error type define_error!(Error);
/// A function that will always fail
fn will_fail() -> Result<(), Error
// Will panic with a nice error if let Err(e) = will_fail() { eprintln!("Error: {:?}", e); panic!("Fatal error") } ```
This crate currently has one feature gate:
- force_backtrace
(disabled by default): If force_backtrace
is enable, the backtrace is always captured,
regardless whether RUST_BACKTRACE
is set or not.
