Struct RegexGenerator 

pub struct RegexGenerator { /* private fields */ }

Generator for strings matching a regex pattern. Created by from_regex().

By default generates strings that contain a match. Use fullmatch() to require the entire string to match.

Implementations

impl RegexGenerator

pub fn fullmatch(self, fullmatch: bool) -> Self

Set whether the entire string must match the pattern, not just contain a match.

pub fn alphabet(self, alphabet: CharactersGenerator) -> Self

Constrain which characters may appear in generated strings.

Trait Implementations

impl Generator<String> for RegexGenerator

fn map<U, F>(self, f: F) -> Mapped<T, U, F, Self>

where Self: Sized, F: Fn(T) -> U + Send + Sync,

Transform generated values using a function.

fn flat_map<U, G, F>(self, f: F) -> FlatMapped<T, U, G, F, Self>

where Self: Sized, G: Generator<U>, F: Fn(T) -> G + Send + Sync,

Generate a value, then use it to choose or configure another generator.

fn filter<F>(self, predicate: F) -> Filtered<T, F, Self>

where Self: Sized, F: Fn(&T) -> bool + Send + Sync,

Only keep generated values that satisfy the predicate.

fn boxed<'a>(self) -> BoxedGenerator<'a, T>

where Self: Sized + Send + Sync + 'a,

Convert this generator into a type-erased boxed generator.
