Struct proptest::num::f64::Any[][src]

#[must_use = "strategies do nothing unless used"]
pub struct Any(_);

Strategies which produce floating-point values from particular classes. See the various Any-typed constants in this module.

Note that this usage is fairly advanced and primarily useful to implementors of algorithms that need to handle wild values in a particular way. For testing things like graphics processing or game physics, simply using ranges (e.g., -1.0..2.0) will often be more practical.

Any can be OR'ed to combine multiple classes. For example, POSITIVE | INFINITE will generate arbitrary positive, non-NaN floats, including positive infinity (but not negative infinity, of course).

If neither POSITIVE nor NEGATIVE has been OR'ed into an Any but a type to be generated requires a sign, POSITIVE is assumed. If no classes are OR'ed into an Any (i.e., only POSITIVE and/or NEGATIVE are given), NORMAL is assumed.

The various float classes are assigned fixed weights for generation which are believed to be reasonable for most applications. Roughly:
