[−][src]Crate simple_error

A simple error type backed by a string.

This crate provides a SimpleError type, which implements std::error::Error. The underlying is a String as the error message.

It should be used when all you care about is an error string.

It should not be used when you want to programmatically handle different kinds of an error.

Macros

bail	Helper macro for returning a `SimpleError` constructed from either a `Into<SimpleError>`, a string slice, or a formatted string.
map_err_with	Map a result type error to simple error with format
require_with	Helper macro for unwrapping `Option` values while returning early with a newly constructed `SimpleError` if the value of the expression is `None`. Can only be used in functions that return `Result<_, SimpleError>`.
simple_error	Construct an ad-hoc `SimpleError` from a string.
try_with	Helper macro for unwrapping `Result` values while returning early with a newly constructed `SimpleError` if the value of the expression is `Err`. Can only be used in functions that return `Result<_, SimpleError>`.

A type that represents a simple error.

Result type in which the error is a simple error
