Struct sample_std::Regex

pub struct Regex {
    pub dist: Regex,
    pub re: Regex,
}

Sample strings given a “valid” regular expression.

Shrinking is done by shortening the string and testing if the expression still matches.

Fields

dist: Regex

re: Regex

Implementations

impl Regex

pub fn new(pattern: &str) -> Self

Create a new Regex sampler with the given pattern string.

Trait Implementations

impl Clone for Regex

fn clone(&self) -> Regex

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Regex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Sample for Regex

type Output = String

fn generate(&self, g: &mut Random) -> Self::Output

Randomly generate the requested type.

fn shrink(&self, v: Self::Output) -> Shrunk<'_, Self::Output>

Shrink the given value into a “smaller” value. Defaults to an empty iterator (which represents that the value cannot be shrunk).

fn try_convert<T, I, F>(self, from: F, try_into: I) -> TryConvert<Self, F, I>where Self: Sized, F: Fn(Self::Output) -> T + Copy, I: Fn(T) -> Option<Self::Output>,

Convert this sampler into a new sampler with from and try_into functions:

fn zip<OS>(self, other: OS) -> Zip<Self, OS>where Self: Sized, OS: Sample,

“Zip” two samplers together. Functionally equivalent to (self, other).

fn chain_resample<F, RS>( self, transform: F, subsamples: usize ) -> ChainResample<Self, F>where Self: Sized, F: Fn(Self::Output) -> RS, RS: Sample,

“Resampling” method for chaining samplers.
