gatekeeper-core
gatekeeper-core
is a library for interfacing with gatekeeper NFC tags.
If you're interested in making a project using gatekeeper, you're free to
use this library, but you might prefer using
gatekeeper-members
which adds support for validating tags against the gatekeeper server,
getting secrets from environment variables, and provides a higher-level
interface that should reduce boilerplate for most common usecases.
Example
It's pretty easy to connect to a reader and find tags:
let mut gatekeeper_reader =
GatekeeperReader::new("pn532_uart:/dev/ttyUSB0".to_string(), realm)
.expect("Failed to open gatekeeper");
for tag in gatekeeper_reader.get_nearby_tags() {
if let Ok(association_id) = tag.authenticate() {
println!("Association ID for tag: {association_id}");
}
}
