Struct Output 

pub struct Output { /* private fields */ }

Aggregate output of all tests run by this handler.

Implementations

impl Output

pub fn blank() -> Self

Instantiates an empty “output”. Useful for merging.

pub fn success( &mut self, name: impl AsRef<str>, mdata: TestMdata, iters: NonZero<usize>, timings: Timings, )

Reports a success and adds it to this run’s Output.

pub fn failure( &mut self, name: impl AsRef<str>, mdata: Option<TestMdata>, attempted_iters: Option<NonZero<usize>>, kind: FailKind, )

Reports a failure and adds it to this run’s Output. If this test was tried with some number of iterations (i.e. this was not a version mismatch or skipped test), it should be reported also.

Using the fail!() macro is usually more convenient.

pub fn is_empty(&self) -> bool

True if no tests executed this run.

pub fn sort(&mut self)

Sorts the runs in the output in the order that we want them printed.

pub fn merge<'a>(&mut self, other: Self, pref_other: impl Into<Option<&'a str>>)

Merges the output of two runs, appending a prefix to the results of the new run. To be used in conjunction with Output::blank(), or else only some tests will have a prefix set.

pub fn compare_perf(self, baseline: Self) -> PerfReport

Evaluates the performance of self against baseline. The latter is taken as the comparison point, i.e. a positive resulting PerfReport means that self performed better.

Panics

self and baseline are assumed to have the iterations field on all TestMdatas set to Some(_) if the TestMdata is present itself.

Trait Implementations

impl Clone for Output

fn clone(&self) -> Output

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Output

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

Formats the value using the given formatter.

impl Default for Output

fn default() -> Output

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Output

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Output

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

Formats the value using the given formatter.

impl Serialize for Output

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
