Crates.io

High-level safe Rust bindings for libnfc.

This crate provides a safe wrapper around nfc1-sys.

In contrast to nfc, this crate additionally provides:

  • Extra safety
    • No exposed raw pointers
    • No .unwrap() where the it is not guaranteed to succeed
    • Enums for well-known constants
  • Result<T, Error> for methods which can fail
  • Everything nfc1-sys provides, which nfc-sys does not
    • Some internal methods exposed (such as pn53x_*, which are useful for accessing manufacturer-specific features in NFC devices)

Usage

Add nfc1 as a dependency in your project's Cargo.toml file:

[dependencies]
nfc1 = "0.5"

Import the nfc1 crate in your project, then you can use all the wrapped functions from libnfc.

See the libnfc wiki or libnfc 1.8.0 examples for information on how to use libnfc.

Usage example

fn main() -> nfc1::Result<()> {
	println!("libnfc v{}", nfc1::version());

	let mut context = nfc1::Context::new()?;
	let mut device = context.open()?;

	println!("NFC device {:?} opened through connection {:?}", device.name(), device.connstring());
	println!("- Initiator modulations: {:?}", device.get_supported_modulation(nfc1::Mode::Initiator)?);
	println!("- Target modulations: {:?}", device.get_supported_modulation(nfc1::Mode::Target)?);

	Ok(())
}
