Lib.rs

Support code to ease the process of generating bag thresholds.

NOTE: this assume the runtime implements pallet_staking::Config, as it requires an implementation of the traits frame_support::traits::Currency and CurrencyToVote.

The process of adding bags to a runtime requires only four steps.

1. Update the runtime definition.

   parameter_types!{
        pub const BagThresholds: &'static [u64] = &[];
   }
   
   impl pallet_bags_list::Config for Runtime {
        // <snip>
        type BagThresholds = BagThresholds;
   }
   

2. Write a little program to generate the definitions. This program exists only to hook together the runtime definitions with the various calculations here. Take a look at utils/frame/generate_bags/node-runtime for an example.

3. Run that program:

   $ cargo run -p node-runtime-generate-bags -- --total-issuance 1234 --minimum-balance 1
   

output.rs ```

4. Update the runtime definition.

   + mod output;
   - pub const BagThresholds: &'static [u64] = &[];
   + pub const BagThresholds: &'static [u64] = &output::THRESHOLDS;
