Usage Examples
Quick Reference
Import Patterns
// Using raw fakers with explicit locale
use fake::faker::name::raw::*;
use fake::locales::*;
let name: String = Name(EN).fake();
// Using convenient English locale functions
use fake::faker::name::en::*;
let name: String = Name().fake();
// Using Faker for defaults
use fake::{Faker, Fake};
let anything: YourType = Faker.fake();Common Patterns
| Pattern | Description | Example |
|---|---|---|
Faker.fake() |
Default value for type | let s: String = Faker.fake(); |
(min..max).fake() |
Value within range | let n: u32 = (1..100).fake(); |
Faker(locale).fake() |
Localized faker | Name(ZH_CN).fake() |
(Faker, len).fake() |
Collection with size | let v: Vec<u32> = (Faker, 5..10).fake(); |
fake::vec![...] |
Collection macro | fake::vec![String as Name(EN); 10] |
