Module proptest::prelude

Re-exports the most commonly-needed APIs of proptest.

This module is intended to be wildcard-imported, i.e., use proptest::prelude::*;. Note that it re-exports the whole crate itself under the name prop, so you don't need a separate use proptest; line.

In addition to Proptest's own APIs, this also reexports a small portion of the rand crate sufficient to easily use prop_perturb and other functionality that exposes random number generators. Please note that this is will always be a direct reexport; using these in preference to using the rand crate directly will not provide insulation from the upcoming revision to the rand crate.

Modules

prop	Re-exports the entire public API of proptest so that an import of prelude allows simply writing, for example, prop::num::i32::ANY rather than proptest::num::i32::ANY plus a separate use proptest;.

Macros

prop_assert	Similar to assert! from std, but returns a test failure instead of panicking if the condition fails.
prop_assert_eq	Similar to assert_eq! from std, but returns a test failure instead of panicking if the condition fails.
prop_assert_ne	Similar to assert_ne! from std, but returns a test failure instead of panicking if the condition fails.
prop_assume	Rejects the test input if assumptions are not met.
prop_compose	Convenience to define functions which produce new strategies.
prop_oneof	Produce a strategy which picks one of the listed choices.
proptest	Easily define proptest tests.

Structs

BoxedStrategy	A boxed Strategy trait object as produced by Strategy::boxed().
Just	A Strategy which always produces a single value value and never simplifies.
ProptestConfig	Configuration for how a proptest test should be run.
SBoxedStrategy	A boxed Strategy trait object which is also Sync and Send, as produced by Strategy::sboxed().

Enums

TestCaseError

Errors which can be returned from test cases to indicate non-successful completion.

Traits

Arbitrary	Arbitrary determines a canonical Strategy for the implementing type.
Rng	An automatically-implemented extension trait on RngCore providing high-level generic methods for sampling values and other convenience methods.
RngCore	The core of a random number generator.
Strategy	A strategy for producing arbitrary values of a given type.

Functions

any	Generates a Strategy producing Arbitrary values of A. Unlike arbitrary, it should be used for being explicit on what A is. For clarity, this may be a good idea.
any_with	Generates a Strategy producing Arbitrary values of A with the given configuration arguments passed in args. Unlike arbitrary_with, it should be used for being explicit on what A is. For clarity, this may be a good idea.
