Module proptest::prelude[−][src]

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;`.

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.
