Provided methods

fn or<U>(self, other: U) -> OrSampler<Self, U> where
    Self: Sized,
    U: Sampler<T>, 

Returns the sampler that samples a trace if self or other decides to sample it.

fn and<U>(self, other: U) -> AndSampler<Self, U> where
    Self: Sized,
    U: Sampler<T>, 

Returns the sampler that samples a trace if both of self and other decides to sample it.

fn boxed(self) -> BoxSampler<T> where
    Self: Sized + Send + Sync + 'static, 

Converts into BoxSampler.
