Struct CharSet

struct CharSet(BTreeSet<char>);

A set of characters used to generate a password. This set is backed by a BTreeSet to have consistent ordering between runs. This is not important during normal execution, but it’s necessary for the tests to be repeatable. To create an instance, use CharSet::default()

Tuple Fields

0: BTreeSet<char>

Implementations

impl CharSet

pub fn include(self, other: impl IntoIterator<Item = char>) -> Self

Includes the given characters in the set. Any duplicate items will be ignored

pub fn include_if( self, predicate: bool, other: impl IntoIterator<Item = char>, ) -> Self

Includes the given characters in the set if the predicate is true. Any duplicate items will be ignored

pub fn exclude_if<'a>( self, predicate: bool, other: impl IntoIterator<Item = &'a char>, ) -> Self

Excludes the given characters from the set. Any missing items will be ignored

Trait Implementations

impl Clone for CharSet

fn clone(&self) -> CharSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for CharSet

fn default() -> CharSet

Returns the “default value” for a type.

impl Distribution<char> for CharSet

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> char

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T>

where R: Rng, Self: Sized,

Create an iterator that generates random values of T, using rng as the source of randomness.

fn map<F, S>(self, func: F) -> DistMap<Self, F, T, S>

where F: Fn(T) -> S, Self: Sized,

Create a distribution of values of ‘S’ by mapping the output of Self through the closure F

impl<'a> IntoIterator for &'a CharSet

type Item = char

The type of the elements being iterated over.

type IntoIter = Copied<Iter<'a, char>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
