displaydoc-lite

Implement the Display trait using your standard doc comments.

This crate is a lite version of the popular crate displaydoc. It provides the same functionality but using a declarative macro instead and not depending on syn or quote.

This crate is also usable in no_std environments. No additional features are required for that.

Note: displaydoc-lite still has a proc-macro as a dependency, but it's very tiny and doesn't have any dependencies.

Example

use displaydoc_lite::displaydoc;

displaydoc! {
    #[derive(Debug)]
    pub enum DataStoreError {
        /// data store disconnected
        Disconnect,
        /// the data for key is not available
        Redaction,
        /// invalid header
        InvalidHeader,
        /// unknown data store error
        Unknown,
    }
}

Support for interpolating fields is planed, but currently not implemented.
