Crate musli_tests
source ·Expand description
Helper utilities for ensuring that musli is safe to use and behaves as expected.
This does include a fairly sophisticated benchmarking suite.
Benchmarking
Now this includes the extra
category, which requires model_minimal
. This
is not exactly a fair comparison, because it compares serialization formats
which were designed to model data that others are not capable off.
The exact tradeoff can be seen by comparing the feature model_full
with
model_minimal
.
cargo bench --no-default-features --features musli,full,extra,model_minimal,simdutf8
To run benchmarks for serialization suites which do support all features, do:
cargo bench --features full
Fuzz testing
This comes with the fuzz
binary which can do the following things.
Run serialization for a long time against a lot of random data. Both with and without miri. When run with miri, the size of the datasets is drastically reduced.
cargo run --bin fuzz
cargo +nightly miri run --bin fuzz
Run deserialization against randomly generated bytes. Both with and without miri. When run with miri, the size of the datasets is drastically reduced.
cargo run --bin fuzz -- --random
cargo +nightly miri run --bin fuzz -- --random
Note you can add the running of optional crates by enabling its corresponding feature, such as
--features bincode
.
Potential security issues discovered by this crate
dlhn
: Allocating and initializing large arrays based on untrusted input (DoS): dlhn#11.
Size comparison
To perform a one-off size comparison:
cargo run --bin fuzz -- --size
This will for now just take the first generated field of a given type, serialize it, and print out its size. In the future it will perform an average over the entire set with more statistics.
Modules
Macros
- Super macro to help build benchmarkers without too much of a fuzz.
- Call the given macro with the existing feature matrix.
- Only expand
$block
if the given test is supported by this framework. - Roundtrip the given expression through all supported formats.
Functions
- Build common RNG.
