Crate custom_error 

Rust custom error

This crate contains a custom_error! macro that should make it easier to define custom errors without having to write a lot of boilerplate code.

Crate features

nostd

This crate supports no-std: it can be built without the rust standard library. To use the no-std version, disable the std feature in this crate in your Cargo.toml :

[dependencies]
custom_error = { version = "1", default-features = false } # nostd compatible

unstable

There is also an unstable feature that implements the nostd error trait on AllocError and TryReserveError in no-std.

Macros

custom_error

Constructs a custom error type.

Traits

Error

Use the Error trait from std by default. Error is a trait representing the basic expectations for error values, i.e., values of type E in Result<T, E>.
