Fake

Rust 库，用于生成伪造数据。

安装

默认

[dependencies]
fake = { version = "2.9.2", features = ["derive"] }

可用功能

• derive：如果您想使用 #[derive(Dummy)]
• 支持的包功能标志
  • chrono
  • chrono-tz
  • http
  • uuid
  • bigdecimal (通过 bigdecimal-rs)
  • rust_decimal
  • random_color
  • geo
  • semver
  • serde_json
  • time
  • zerocopy
  • glam
• always-true-rng：暴露 AlwaysTrueRng
• maybe-non-empty-collections：允许使用 AlwaysTrueRng 生成非空集合

使用方法

use fake::{Dummy, Fake, Faker};
use rand::rngs::StdRng;
use rand::SeedableRng;

#[derive(Debug, Dummy)]
pub struct Foo {
    #[dummy(faker = "1000..2000")]
    order_id: usize,
    customer: String,
    paid: bool,
}

#[derive(Debug, Dummy)]
struct Bar<T> {
    field: Vec<T>,
}

fn main() {
    // type derived Dummy
    let f: Foo = Faker.fake();
    println!("{:?}", f);

    let b: Bar<Foo> = Faker.fake();
    println!("{:?}", b);

    // using `Faker` to generate default fake value of given type
    let tuple = Faker.fake::<(u8, u32, f32)>();
    println!("tuple {:?}", tuple);
    println!("String {:?}", Faker.fake::<String>());

    // types U can used to generate fake value T, if `T: Dummy<U>`
    println!("String {:?}", (8..20).fake::<String>());
    println!("u32 {:?}", (8..20).fake::<u32>());

    // using `faker` module with locales
    use fake::faker::name::raw::*;
    use fake::locales::*;

    let name: String = Name(EN).fake();
    println!("name {:?}", name);

    let name: String = Name(ZH_TW).fake();
    println!("name {:?}", name);

    // using convenient function without providing locale
    use fake::faker::lorem::en::*;
    let words: Vec<String> = Words(3..5).fake();
    println!("words {:?}", words);

    // using macro to generate nested collection
    let name_vec = fake::vec![String as Name(EN); 4, 3..5, 2];
    println!("random nested vec {:?}", name_vec);

    // fixed seed rng
    let seed = [
        1, 0, 0, 0, 23, 0, 0, 0, 200, 1, 0, 0, 210, 30, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
        0, 0, 0, 0,
    ];
    let ref mut r = StdRng::from_seed(seed);
    for _ in 0..5 {
        let v: usize = Faker.fake_with_rng(r);
        println!("value from fixed seed {}", v);
    }
}
