Macro brush_lang::declare_derive_storage_trait

macro_rules! declare_derive_storage_trait {
    ($derive_name:ident,$trait_name:ident,$trait_field_specifier:ident) => { ... };
}

This macro_rule generates a procedural derive macro for storage trait.

The first argument is the name of the procedural function. The second argument is the name of the trait for which derive will be generated. The third argument is the name of the marker for the derive macro. This marker specifies for derive macro which field will be returned by the implementation for the storage trait.

An example of the usage of this macro can be found in derive folder of any contract implemented by this library. For example OwnableStorage.
