Expand description

Serialize a value into bytes.

ยงExamples

// Bring serde Serialize/Deserialize derivable traits into scope.
use serde::Serialize;

// Define custom struct.
#[derive(Serialize)]
struct MyStruct {
    name: String,
    score: u32,
}

// Create value to serialize.
let value = MyStruct {
   name: "Ferris".to_owned(),
   score: 42,
};

// Serialize value into bytes.
let bytes = shaft::to_bytes(&value).expect("serialization error");
