When it comes to data serialization and deserialization in Rust, there is no doubt we are talking about serde (https://crates.io/crates/serde). Serde, from serialization and deserialization, gives us a unique tool to be able to transform our data structures to JSON, TOML, XML, or any other serializable format. Let's see how it works.
We start with a simple structure:
struct MyData { field1: String, field2: u32, field3: Vec<u8>,}
And we add serde and serde_derive as dependencies to our Cargo.toml file:
[dependencies]serde = "1.0.0"serde_derive = "1.0.0"
Then, in our main.rs file, we just need to import the crates using extern crate and derive the Serialize trait for our structure:
extern crate serde; ...
