rustfmt.toml

# Rustfmt configuration for consistent code formatting
#
# IMPORT ORGANIZATION STANDARD:
# Imports have 3 groups, with a blank line between groups:
# 1. Standard library (std::, core::, alloc::)
# 2. External crates (for example common, rayon, smallvec)
# 3. Local imports: self::, then super::, then crate::, with no blank line between them
#
# Each `use` statement imports from one module. rustfmt sorts the statements in each group.
#
# Example:
#   use std::io;
#   use std::str::FromStr;
#
#   use common::bitboard::Square;
#   use rayon::prelude::*;
#
#   use super::helper::Helper;
#   use crate::board::Board;
#   use crate::chess_move::ChessMove;
#
# `make fmt` applies this order with the nightly-only options group_imports and
# imports_granularity. It also wraps comments at 100 columns (wrap_comments and
# comment_width). The Makefile passes these options, so that stable rustfmt
# does not warn about them. `make lint` checks the order.
