GLOBAL ID CREATOR
this is a small procedural macro which can be use in global to create a list of constant with the id is u8. increace by 1 for each constant created
use global_id_creator_macro::ntl_create_global_id;
pub enum Global {
Id(u8)
}
ntl_create_global_id!(Global, CONST_A, CONST_B, CONST_C, CONST_D, CONST_E);
fn main() {
println!("CONST_A = {:?}", CONST_A);
println!("CONST_B = {:?}", CONST_B);
println!("CONST_C = {:?}", CONST_C);
println!("CONST_D = {:?}", CONST_D);
println!("CONST_E = {:?}", CONST_E);
}
output:
CONST_A = Id(100)
CONST_B = Id(101)
CONST_C = Id(102)
CONST_D = Id(103)
CONST_E = Id(104)
the macro will be expanded like this:
pub const CONST_A: Global = Global::Id(100);
pub const CONST_A: Global = Global::Id(101);
pub const CONST_A: Global = Global::Id(102);
pub const CONST_A: Global = Global::Id(103);
pub const CONST_A: Global = Global::Id(104);
This crate is just use for my personal project, so it maybe not fit which your need
