# 
# Script to regenerate SQLx query cache for monero-rpc-pool
# 
# This script:
# 1. Creates a temporary SQLite database in a temp directory
# 2. Runs all database migrations to set up the schema
# 3. Regenerates the SQLx query cache (.sqlx directory)
# 4. Cleans up temporary files automatically
#
# Usage:
#   ./regenerate_sqlx_cache.sh
#
# Requirements:
# - cargo and sqlx-cli must be installed
# - Must be run from the monero-rpc-pool directory
# - migrations/ directory must exist with valid migration files
#
# The generated .sqlx directory should be committed to version control
# to enable offline compilation without requiring DATABASE_URL.
