[dependabot]

Bumps criterion from 0.3.3 to 0.3.4.

Changelog

Sourced from criterion's changelog.

[0.3.4] - 2021-01-24

Added

• Added support for benchmarking async functions
• Added with_output_color for enabling or disabling CLI output coloring programmatically.

Fixed

• Criterion.rs will now give a clear error message in case of benchmarks that take zero time.
• Added some extra code to ensure that every sample has at least one iteration.
• Added a notice to the --help output regarding "unrecognized option" errors.
• Increased opacity on violin charts.
• Fixed violin chart X axis not starting at zero in the plotters backend.
• Criterion.rs will now automatically detect the right output directory.

Deprecated

• Criterion::can_plot is no longer useful and is deprecated pending deletion in 0.4.0.
• Benchmark and ParameterizedBenchmark were already hidden from documentation, but are now formally deprecated pending deletion in 0.4.0. Callers should use BenchmarkGroup instead.
• Criterion::bench_function_over_inputs, Criterion::bench_functions, and Criterion::bench were already hidden from documentation, but are now formally deprecated pending deletion in 0.4.0. Callers should use BenchmarkGroup instead.
• Three new optional features have been added; "html_reports", "csv_output" and "cargo_bench_support". These features currently do nothing except disable a warning message at runtime, but in version 0.4.0 they will be used to enable HTML report generation, CSV file generation, and the ability to run in cargo-bench (as opposed to cargo-criterion). "cargo_bench_support" is enabled by default, but "html_reports" and "csv_output" are not. If you use Criterion.rs' HTML reports, it is recommended to switch to cargo-criterion. If you use CSV output, it is recommended to switch to cargo-criterion and use the --message-format=json option for machine-readable output instead. A warning message will be printed at the start of benchmark runs which do not have "html_reports" or "cargo_bench_support" enabled, but because CSV output is not widely used it has no warning.
