Lib.rs

onlyerror is a procedural macro. It will run at compile time and transform your program's source code.

Adding onlyerror macro(s) as a dependency

Run this command in a terminal, in your project's directory:

cargo add onlyerror

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

onlyerror = "0.1.5"

You may need to import the macro(s) with use onlyerror::*.

Read the onlyerror documentation.
