//! Configuration types for virtual MTP devices.

/// # Example
///
/// ```rust
/// use std::path::PathBuf;
/// use std::time::Duration;
/// use mtp_rs::transport::virtual_device::config::{VirtualDeviceConfig, VirtualStorageConfig};
///
/// let config = VirtualDeviceConfig {
///     manufacturer: "Google".into(),
