Derive Macro ConstAssoc 

#[derive(ConstAssoc)]
{
    // Attributes available to this derive:
    #[const_assoc]
}

Adds associated constants to a type via an inherent impl block.

Example

#[derive(mkutils_macros::ConstAssoc)]
#[const_assoc(pub MAX_SIZE: usize = 1024)]
#[const_assoc(DEFAULT_NAME: &str = "unnamed")]
struct MyStruct;

// adds
// ```rust
// impl MyStruct {
//     pub const MAX_SIZE: usize = 1024;
//     const DEFAULT_NAME: &str = "unnamed";
// }
// ```
// as can be seen in

std::assert_eq!(MyStruct::MAX_SIZE, 1024);
std::assert_eq!(MyStruct::DEFAULT_NAME, "unnamed");
