Crate serde_magnus
source ·Expand description
serde_magnus
converts between Rust and Ruby data structures using Serde and Magnus.
The serialize
function converts from a Rust type implementing the serde::Serialize
trait into a Ruby equivalent.
use serde::{Serialize, Deserialize};
use magnus::{eval, Value};
use serde_magnus::serialize;
#[derive(Serialize, Deserialize, PartialEq, Debug)]
struct Post {
title: String,
content: String,
author: Author,
tags: Vec<String>
}
#[derive(Serialize, Deserialize, PartialEq, Debug)]
struct Author {
name: String,
email_address: String
}
let post = Post {
title: "Spring carnival planning update".into(),
content: "Here's what's new.".into(),
author: Author {
name: "Martha".into(),
email_address: "martha@example.com".into()
},
tags: vec![
"carnival".into(),
"update".into()
]

post == {

author: {

deserialize
converts from a Ruby value to a Rust type implementing serde::Deserialize
.
use serde_magnus::deserialize;
let post: RHash = eval!(r#"
{
title: "Spring carnival planning update",
content: "Here's what's new.",
author: {
name: "Martha",
email_address: "martha@example.com"
},
tags: ["carnival", "update"]
}
"#)?;
let post: Post = deserialize(post)?;
assert_eq!(
Post {
title: "Spring carnival planning update".into(),
content: "Here's what's new.".into(),
author: Author {
name: "Martha".into(),
email_address: "martha@example.com".into()
},
tags: vec![
"carnival".into(),
"update".into()
