Macro impl_basic

macro_rules! impl_basic {
    ($s:ident, $name:expr) => { ... };
}

Defines a macro for creating structures with basic functionality.

This macro generates a structure that includes a single usize field, implements several traits, and provides methods related to configuration and naming. For any given identifier and a name, the generated structure derives traits for debugging, cloning, copying, equality comparison, and hashing. It includes a method to create an instance from a configuration, specifically fetching a “cost” value, defaulting to 1 if unspecified. There’s also a method for obtaining the name of the structure as a static string. Additionally, it implements the Display trait for formatted output of the structure’s name, and provides a default implementation that creates an instance using a default configuration.
