# Rust Formatting Configuration
# This file defines explicit formatting rules for the project.
# Run with: cargo fmt
# Check with: cargo fmt --check
#
# Note: We only use stable rustfmt options here. Unstable options would require
# nightly toolchain and are commented out below for reference.

# Edition to use for parsing (matches Cargo.toml)
edition = "2024"

# Maximum line width
max_width = 100

# Use spaces for indentation
hard_tabs = false
tab_spaces = 4

# Import ordering
reorder_imports = true
reorder_modules = true

# Keep newlines for readability
newline_style = "Unix"

# Function signatures
fn_params_layout = "Tall"

# Match arm formatting
match_block_trailing_comma = true

# Use field init shorthand where possible
use_field_init_shorthand = true

# Merge derives into a single attribute
merge_derives = true

# Use try! shorthand (?)
use_try_shorthand = true

# Chain formatting
chain_width = 60

# Array formatting
array_width = 60
