Example
The following example shows off reading from ADS-B bytes from a demodulation server into our Frame
struct and then executing the fmt::Display
Trait for display of information.
use hex;
use Frame;
use DekuContainerRead;
let bytes = hex!;
let frame = from_bytes.unwrap.1;
assert_eq!;

Testing
Test data was generated using a rtl-sdr with dump1090-fa
.
> cargo test
For testing this library, you can run our app 1090
with the following options for exiting program
on missing fmt::Display
or bytes protocol decode.
> cd ../apps
> cargo r --release --bin 1090 -- --debug --disable-airplanes --panic-decode --panic-display
This library is also fuzzed, ensuring no panic when parsing from demodulated bytes.
> cargo fuzz run fuzz_target_1
fmt
> cargo +nightly fmt
Benchmark
Benchmarking is done against a file containing 215606
ADS-B messages: lax-messages.txt.
Quick math (215606 / 692.80)
says the average speed of decoding is ~311.21 ms
a message.
A ~3%
speedup can be gained on some systems by using RUSTFLAGS="-C target-cpu=native"
> cargo bench
lax_messsages time: [680.70 ms 692.82 ms 704.99 ms]
Derivation
Derived from Aeronautical Telecommunications Volume IV: Surveillance and Collision Avoidance Systems, Fifth Edition and ICAO 9871.
