Struct Filter

#[must_use = "strategies do nothing unless used"]
pub struct Filter<S, F> { /* private fields */ }

Static version of strategy::Filter.

Implementations

impl<S, F> Filter<S, F>

fn new(source: S, whence: Reason, filter: F) -> Self

Adapt strategy source to reject values which do not pass filter, using whence as the reported reason/location.
