Crate clierr

A small library which provides convenient, non-panicking error handling for small CLI scripts.

Macros

ccheck

Like assert! but instead of panicking it early-returns an Error with a given description (which can be specified using format_args! syntax).

ctry

Like try!, but in the error case the error is wrapped in an Error with a given description (which can be specified using format_args! syntax).

Structs

Error

A minimalist error type to use in CLI scripts: it wraps an arbitrary cause which implements std::error::Error and a description for the Display implementation.

Traits

DescribeErr

A trait which enables adding a description to any Result by wrapping its error type in an Error

Functions

run_and_exit

Runs a Result-returning function and exits the process with 0 if successful.
