Function db_migrate 

pub async fn db_migrate(url: &str, action: &str, steps: usize) -> Result<()>

Run database migrations.

Manages database schema migrations using SQLx auto-migration. Supports applying migrations, checking status, and rollback guidance.

Arguments

• url - Database connection URL
• action - Migration action: “apply”, “rollback”, or “status”
• steps - Number of steps for rollback (currently requires manual rollback)

Actions

• apply: Initialize schema and apply migrations
• status: Check current schema state
• rollback: Show manual rollback instructions

Note

CeleRS uses SQLx auto-migration. For rollbacks, restore from database backup.

Examples

// Apply migrations
db_migrate("postgresql://localhost/celers", "apply", 0).await?;

// Check status
db_migrate("postgresql://localhost/celers", "status", 0).await?;
