I built mtp-rs, a pure-Rust async MTP/PTP library. No libmtp, no libusb, no FFI. Built on nusb.

(Quick refresher: MTP is the protocol your phone uses when you plug it into a computer to copy files.)

It's 1.06–4.04x faster than libmtp across all operations I tested, and absurdly more consistent. At 100 MB downloads, mtp-rs std dev was 4.7 ms vs libmtp's 4,612 ms. (That's 1000x more consistent!)

See here:

It has two API layers: mtp:: for Android phones and media devices, ptp:: for cameras and low-level protocol work.

Here is how to use the API:

use mtp_rs::mtp::MtpDevice;

let device = MtpDevice::open_first().await?;
for storage in device.storages().await? {
    for file in storage.list_objects(None).await? {
        println!("{} {}", if file.is_folder() { "📁" } else { "📄" }, file.filename);
    }
}

I've tested it on a Pixel 9 Pro XL, Samsung Galaxy S23 Ultra, and a Fujifilm X-T4. It handles device quirks automatically (Android's broken recursive listing, Samsung's root listing errors, Fuji advertising write support it doesn't have).

I need community help testing with more devices. The test suite is designed so only read-only tests run by default, so it won't mess with your files. If you have an MTP device and 5 minutes:

• GitHub
• crates.io
• docs.rs
