Trait Implementations

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
The value tree generated by this Strategy.
The type of value used by functions under test generated by this Strategy. Read more
Generate a new value tree from the given runner. Read more
Returns a strategy which produces values transformed by the function fun. Read more
Returns a strategy which produces values of type O by transforming Self with Into<O>. Read more
Returns a strategy which produces values transformed by the function fun, which is additionally given a random number generator. Read more
Maps values produced by this strategy into new strategies and picks values from those strategies. Read more
Maps values produced by this strategy into new strategies and picks values from those strategies while considering the new strategies to be independent. Read more
Similar to prop_ind_flat_map(), but produces 2-tuples with the input generated from self in slot 0 and the derived strategy in slot 1. Read more
Returns a strategy which only produces values accepted by fun. Read more
Returns a strategy which only produces transformed values where fun returns Some(value) and rejects those where fun returns None. Read more
Returns a strategy which picks uniformly from self and other. Read more
Generate a recursive structure with self items as leaves. Read more
Erases the type of this Strategy so it can be passed around as a simple trait object. Read more
Wraps this strategy to prevent values from being subject to shrinking. Read more
The type of the value produced by this ValueTree.
Returns the current value.
Attempts to simplify the current value. Notionally, this sets the “high” value to the current value, and the current value to a “halfway point” between high and low, rounding towards low. Read more
Attempts to partially undo the last simplification. Notionally, this sets the “low” value to one plus the current value, and the current value to a “halfway point” between high and the new low, rounding towards low. Read more
