Module sample

Strategies for generating values by taking samples of collections.

Note that the strategies in this module are not native combinators; that is, the input collection is not itself a strategy, but is rather fixed when the strategy is created.

Structs

• Index
  A stand-in for an index into a slice or similar collection or conceptually similar things.
• IndexStrategy
  Strategy to create Indexes.
• IndexValueTree
  ValueTree corresponding to IndexStrategy.
• Select
  Strategy to produce one value from a fixed collection of options.
• SelectValueTree
  ValueTree corresponding to Select.
• Selector
  A value for picking random values out of iterators.
• SelectorStrategy
  Strategy to create Selectors.
• SelectorValueTree
  ValueTree corresponding to SelectorStrategy.
• SizeRange
  The minimum and maximum range/bounds on the size of a collection. The interval must form a subset of [0, std::usize::MAX).
• Subsequence
  Strategy to generate Vecs by sampling a subsequence from another collection.
• SubsequenceValueTree
  ValueTree type for Subsequence.

Functions

• select
  Create a strategy which uniformly selects one value from values.
• size_range
  Creates a SizeRange from some value that is convertible into it.
• subsequence
  Sample subsequences whose size are within size from the given collection values.
