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 theDisplay
-trait forEtrace<MyType>
using theDebug
representation ofMyType
(instead of theDisplay
representation). This way you can pretty-print the underlying error types without the necessity to manually implement theDisplay
-trait for them.
Macros
Defines a custom error with descripion
