Crate ebacktrace

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

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<ErrorKind>> {
    Err(ErrorKind::Testolope)?
}
 
// Will panic with a nice fully-backtraced error
will_fail().unwrap();

Features

This crate currently has one feature gate:

• derive_display (enabled by default): Implements 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.

Macros

Defines a custom error with descripion
