Struct StringGenerator 

pub struct StringGenerator;

Generates random, unique string values from UUIDs. This implementation does provide an invalid value, the empty string.

Provides implementations of:

• Generator - returns random String values.
• GeneratorWithInvalid - returns an invalid, as an ID, String value.
• GeneratorFromStr - ensures validity of a string representation as an String ID.

Trait Implementations

impl Clone for StringGenerator

fn clone(&self) -> StringGenerator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringGenerator

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

Formats the value using the given formatter.

impl Default for StringGenerator

fn default() -> StringGenerator

Returns the “default value” for a type.

impl Generator<String> for StringGenerator

fn next_id(&self) -> String

Generate a new ID, this may be an entirely random value, or as the name implies the next in some logical sequence.

impl GeneratorFromStr<String> for StringGenerator

fn is_valid_value(s: &str) -> bool

Is the value s valid as an ID?

impl GeneratorWithInvalid<String> for StringGenerator

fn invalid_id() -> String

where Self: Sized,

Return a unique value that is not valid as an ID.
