# rustfmt configuration for mux-contracts

# This file pins the formatting rules that `cargo fmt` and the CI fmt-check
# step enforce.  Running `cargo fmt --all` locally will produce output that
# is identical to what the CI `cargo fmt --all -- --check` step expects.

# CI step (ci.yml):
#   - name: cargo fmt
#     run: cargo fmt --all -- --check
