Command line arguments.

This type represents everything the user can specify via CLI args. The main method is from_args which reads the global std::env::args() and parses them into this type.

libtest-mimic supports a subset of all args/flags supported by the official test harness. There are also some other minor CLI differences, but the main use cases should work exactly like with the built-in harness.

Fields

include_ignored: bool

Run ignored and non-ignored tests.

ignored: bool

Run only ignored tests.

test: bool

Run tests, but not benchmarks.

bench: bool

Run benchmarks, but not tests.

list: bool

Only list all tests and benchmarks.

nocapture: bool

No-op, ignored (libtest-mimic always runs in no-capture mode)

exact: bool

If set, filters are matched exactly rather than by substring.

quiet: bool

If set, display only one character per test instead of one line. Especially useful for huge test suites.

This is an alias for --format=terse. If this is set, format is None.

test_threads: Option<usize>

Number of threads used for parallel testing.

logfile: Option<String>

Path of the logfile. If specified, everything will be written into the file instead of stdout.

skip: Vec<String>

A list of filters. Tests whose names contain parts of any of these filters are skipped.

color: Option<ColorSetting>

Specifies whether or not to color the output.

format: Option<FormatSetting>

Specifies the format of the output.

filter: Option<String>

Filter string. Only tests which contain this string are run.

Implementations

impl Arguments

pub fn from_args() -> Self

Parses the global CLI arguments given to the application.

If the parsing fails (due to incorrect CLI args), an error is shown and the application exits. If help is requested (-h or --help), a help message is shown and the application exits, too.

pub fn from_iter<I>(iter: I) -> Selfwhere Self: Sized, I: IntoIterator, I::Item: Into<OsString> + Clone,

Like from_args(), but operates on an explicit iterator and not the global arguments. Note that the first element is the executable name!

Trait Implementations

impl Args for Arguments

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self.

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to Command so it can update self.

impl Clone for Arguments

fn clone(&self) -> Arguments

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CommandFactory for Arguments

fn command<'b>() -> Command

Build a Command that can instantiate Self.

fn command_for_update<'b>() -> Command

Build a Command that can update self.

impl Debug for Arguments

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Arguments

fn default() -> Arguments

Returns the “default value” for a type.

impl FromArgMatches for Arguments

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches ) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches ) -> Result<(), Error>
