Calm I/O Filters

This crate provides proc-macro function attributes which suppress specific I/O error variants. It is an internal implementation detail of the calm_io crate.

lib.rs:

Filtering attributes for the calm_io project.

Procedural macros are required to be kept in a separate crate, as rustc builds them alone and then executes their code during transformation of crates that use them. This crate defines the #[calm_io::FILTER] attributes used to suppress certain I/O errors from signaling failure. !
