Function delete_instance

pub async fn delete_instance(pool: &Pool<MySql>, id: i64) -> Result<()>

Deletes a specific instance from the database.

This function permanently removes an instance record from the database. It’s typically used for cleanup operations after an instance has been terminated, or to remove invalid instances.

Arguments

• pool - Database connection pool for executing the query
• id - Unique identifier of the instance to delete

Returns

• Ok(()) - Successfully deleted the instance
• Err(anyhow::Error) - Failed to delete the instance

Warning

This operation is irreversible and should generally only be performed after ensuring that the actual compute resource has been properly terminated. Otherwise, resource leaks may occur.

Transaction Handling

This function uses a database transaction to ensure atomicity of the operation. If any part of the operation fails, the entire operation is rolled back.
