Struct osrand::RandomString

pub struct RandomString { /* private fields */ }

A random string generator which gets it’s entropy from an internal BufReader wrapping the OS RNG device. This generator may be re-used as many times as required.

Implementations

impl RandomString

pub fn new(flags: &[Flags]) -> Result<Self, Error>

Creates a new random string generator, which gets it’s randomness from an internal BufReader around the OS RNG device. If flags is empty, the full dictionary will be used.

Errors

Returns an io error if there is a problem reading from the RNG device

pub fn with_dict(dict: Vec<char>) -> Result<Self, Error>

Creates a new random string generator with the given dictionary, which gets it’s randomness from an internal BufReader around the OS RNG device. If dict is empty, the full dictionary will be used.

Errors

Returns an io error if there is a problem reading from the RNG device

pub fn from_parts(rng: BufRng, dict: Vec<char>) -> Self

Creates a new random string generator from the provided BufRng rngand theDictionary` dict.

Errors

Returns an io error if there is a problem reading from the RNG device

pub fn get_dictionary(&self) -> &[char]

Gets the dictionary being used by the generator

pub fn set_dictionary(&mut self, dict: Vec<char>)

Sets the dictionary to be used for new random strings

pub fn gen(&mut self, len: usize) -> Result<String, Error>

Generates a random string of the given size

Errors

Returns an io error if there is a problem reading from the RNG device

pub fn append(&mut self, s: String, len: usize) -> Result<String, Error>

Appends len random characters to string s and returns the result

Errors

Returns an io error if there is a problem reading from the RNG device
