使用 diesel-factories。这个库参考 Ruby 的 factory_bot 设计。能够对应像下面这样写:ide
Ruby
factory :country do
name "Denmark"
code "DK"
end
factory :city do
name "Copenhagen"
country
end
Rust
#[derive(Clone, Factory)]
#[factory(model = "Country", table = "countries")]
struct CountryFactory {
pub name: String,
pub code: String,
}
#[derive(Clone, Factory)]
#[factory(model = "City", table = "cities")]
struct CityFactory<'a> {
pub name: String,
pub country: Association<'a, Country, CountryFactory>,
}

使用这个库,用 Rust 对 GPU 编程就很是方便了,这个库提供了一些宏,使得 GPU 编程也能充分利用 Rust 的生态。看下代码长啥样:设计
// The "emu!" macro accepts a chunk of Emu code and
// generates Rust functions that can be called to perform computation on the GPU
emu! {
// Multiply any element in given data by given coefficient
// Data and coefficient must be floats
function multiply(data [f32], coeff f32) {
data[..] *= coeff;
}
// Apply sigmoid function to any element in given data
// Data must be floats
function sig(data [f32]) {
let elem: f32 = data[..];
let res: f32 = 1 / (1 + pow(E, -elem));
data[..] = res;
}
/// Multiplies each element in given data by given coefficient
pub fn multiply(data: &mut Vec<f32>, coeff: &f32);
/// Applies sigmoid to each element in given data
pub fn sig(data: &mut Vec<f32>);
}

今天这个库发布了 v0.7。来看一下性能:
另外还有一个库叫 librsvg,目前也已经用 Rust 重写了。这是各大 Linux 发行版中很基础的一个库,与resvg 比,二者性能上目前各有千秋。
