Crate test

🔬 This is a nightly-only experimental API. (test)

Support code for rustc's built in unit-test and micro-benchmarking framework.

Almost all user code will only be interested in Bencher and black_box. All other interactions (such as writing tests and benchmarks themselves) should be done via the #[test] and #[bench] attributes.

See the Testing Chapter of the book for more details.

Traits

TDynBenchFn

[ Experimental ] Represents a benchmark function.

Functions

assert_test_result	[ Experimental ] Invoked when unit tests terminate. Should panic if the unit test is considered a failure. By default, invokes report() and checks for a 0 result.
black_box	[ Experimental ] A function that is opaque to the optimizer, to allow benchmarks to pretend to use outputs to assist in avoiding dead-code elimination.
convert_benchmarks_to_tests	[ Experimental ]
filter_tests	[ Experimental ]
fmt_bench_samples	[ Experimental ]
iter	[ Experimental ]
list_tests_console	[ Experimental ]
parse_opts	[ Experimental ]
run_test	[ Experimental ]
run_tests	[ Experimental ]
run_tests_console	[ Experimental ]
test_main	[ Experimental ]
test_main_static	[ Experimental ]

Type Definitions

MonitorMsg	[ Experimental ]
OptRes	[ Experimental ] Result of parsing the options.
