From c0ce19236a6167f96d04491f82acd7b863b07188 Mon Sep 17 00:00:00 2001 From: OluRemiFour Date: Wed, 27 May 2026 07:04:14 +0100 Subject: [PATCH 1/2] fix: repair token contract corruption and add .rustfmt.toml - Rewrote contracts/token/src/lib.rs from scratch to eliminate severe merge-conflict corruption (duplicate fn definitions, nested function signatures, mismatched delimiters) - Rebuilt with clean RBAC (bc_forge_admin::require_role), allowance expiration (AllowanceExp key), multi-sig proposal actions, clawback, token locking, two-step ownership transfer, batch_mint, pause/unpause - Added missing TokenError contracterror enum (was dropped in merges) - Fixed events.rs: replaced symbol_short! with Symbol::new for own_accept / own_cancel (>9 char limit) - Rewrote contracts/token/src/test.rs to remove 4x duplicated allowance-expiry test blocks and merged function bodies; corrected mint() call signature to (caller, to, amount) - Added workspace-level .rustfmt.toml (stable-channel options: max_width=100, reorder_imports, newline_style=Unix, edition=2021) - cargo check: clean (no errors) - cargo fmt --all: exit 0, no warnings --- .rustfmt.toml | 16 + contracts/admin/src/lib.rs | 101 +++++-- contracts/token/src/events.rs | 12 +- contracts/token/src/lib.rs | 495 +++++++++++++----------------- contracts/token/src/proptest.rs | 10 +- contracts/token/src/test.rs | 519 ++++++++++---------------------- 6 files changed, 458 insertions(+), 695 deletions(-) create mode 100644 .rustfmt.toml diff --git a/.rustfmt.toml b/.rustfmt.toml new file mode 100644 index 0000000..66d4ce0 --- /dev/null +++ b/.rustfmt.toml @@ -0,0 +1,16 @@ +# bc-forge workspace formatting configuration +# Applied by: cargo fmt --all +# Stable-channel options only. +# See: https://rust-lang.github.io/rustfmt/ + +# ── Line length ────────────────────────────────────────────────────────────── +max_width = 100 + +# ── Imports ─────────────────────────────────────────────────────────────────── +reorder_imports = true +reorder_modules = true + +# ── Misc ────────────────────────────────────────────────────────────────────── +edition = "2021" +newline_style = "Unix" +use_field_init_shorthand = true diff --git a/contracts/admin/src/lib.rs b/contracts/admin/src/lib.rs index 8578a8b..50d87b2 100644 --- a/contracts/admin/src/lib.rs +++ b/contracts/admin/src/lib.rs @@ -5,7 +5,7 @@ #![no_std] -use soroban_sdk::{contracttype, Address, Env, Vec, vec, String}; +use soroban_sdk::{contracttype, vec, Address, Env, String, Vec}; /// Storage keys used by the admin module. #[derive(Clone)] @@ -15,6 +15,14 @@ pub enum AdminKey { Admin, /// Role assignments: (Role, Address) -> bool Role(Role, Address), + /// The pool of administrator addresses for multi-sig. + AdminPool, + /// Minimum signatures required for multi-sig actions. + Threshold, + /// Active proposals: proposal_id -> Proposal. + Proposal(u64), + /// Counter for generating unique proposal IDs. + ProposalIdCounter, } /// Enumeration of available roles. @@ -25,14 +33,6 @@ pub enum Role { Admin = 0, /// Account authorized to mint tokens.
