How to generate additional candid method for icp ledger

Hi all, I want to add new candid method for local test icp ledger

dfinity/ic/blob/master/rs/rosetta-api/icp_ledger/ledger/src/main.rs

use candid::{candid_method, Nat};
use dfn_candid::{candid, candid_one, CandidOne};
use dfn_core::{
    api::{caller, data_certificate, print, set_certified_data, trap_with},
    over, over_async, over_async_may_reject, over_init, printer, setup, stable, BytesS,
};
use dfn_protobuf::protobuf;
use ic_base_types::CanisterId;
use ic_canister_log::{LogEntry, Sink};
use ic_icrc1::endpoints::{convert_transfer_error, StandardRecord};
use ic_ledger_canister_core::{
    archive::{Archive, ArchiveOptions},
    ledger::{
        apply_transaction, archive_blocks, block_locations, find_block_in_archive, LedgerAccess,
    },
    range_utils,
};
use ic_ledger_core::{
    block::{BlockIndex, BlockType, EncodedBlock},
    timestamp::TimeStamp,

This file has been truncated. show original

I can find ledger.did file
but I run “dfx build ledger” in icp_ledger directory, and it exports nothing for my new candid method.
so how can I do that?

I don’t think the did file is autogenerated. I would personally just add it by hand. Is that a feasible approach for you?

in rust canisters, there is a way to autogenerate did file, but I don’t know how to do it in icp ledger official code.

You can probably add this method: https://forum.dfinity.org/t/blog-post-automatically-generate-candid-from-rust/18909t
