## Expand description

Defines the core traits used by Proptest.

## Modules§

- Modified versions of the normal strategy combinators which take specialised traits instead of normal functions.

## Structs§

- A boxed
`Strategy`

trait object as produced by`Strategy::boxed()`

. - Options passed to
`check_strategy_sanity()`

. `Strategy`

and`ValueTree`

filter adaptor.`Strategy`

and`ValueTree`

filter_map adaptor.`ValueTree`

corresponding to`FilterMap`

.- Adaptor that flattens a
`Strategy`

which produces other`Strategy`

s into a`Strategy`

that picks one of those strategies and then picks values from it. - The
`ValueTree`

produced by`Flatten`

. - Adaptor for
`Strategy`

and`ValueTree`

which guards`simplify()`

and`complicate()`

to avoid contract violations. - Similar to
`Flatten`

, but does not shrink the input strategy. - Similar to
`Map`

plus`Flatten`

, but does not shrink the input strategy and passes the original input through. - A
`Strategy`

which always produces a single value value and never simplifies. - A
`Strategy`

which always produces a single value value and never simplifies. If`T`

is`Clone`

, you should use`Just`

instead. - Represents a value tree that is initialized on the first call to any methods.
`Strategy`

and`ValueTree`

map adaptor.`Strategy`

and`ValueTree`

map into adaptor.- Wraps a
`Strategy`

or`ValueTree`

to suppress shrinking of generated values. `Strategy`

perturbation adaptor.`ValueTree`

perturbation adaptor.- Return type from
`Strategy::prop_recursive()`

. - A boxed
`Strategy`

trait object which is also`Sync`

and`Send`

, as produced by`Strategy::sboxed()`

. `Strategy`

shuffle adaptor.`ValueTree`

shuffling adaptor.- Similar to
`Union`

, but internally uses a tuple to hold the strategies. `ValueTree`

type produced by`TupleUnion`

.- A
`Strategy`

which picks from one of several delegate`Stragegy`

s. `ValueTree`

corresponding to`Union`

.

## Traits§

- A value which can be used with the
`prop_shuffle`

combinator. - A strategy for producing arbitrary values of a given type.
- A generated value and its associated shrinker.

## Functions§

- Run some tests on the given
`Strategy`

to ensure that it upholds the simplify/complicate contracts. - Convert a floating-point weight in the range (0.0,1.0) to a pair of weights that can be used with
`Union`

and similar.

## Type Aliases§

- Shorthand for
`LazyJust<T, fn () -> T>`

. - A
**relative**`weight`

of a particular`Strategy`

corresponding to`T`

coupled with`T`

itself. The weight is currently given in`u32`

. - A
**relative**`weight`

of a particular`Strategy`

corresponding to`T`

coupled with`Arc<T>`

. The weight is currently given in`u32`

.
