jsend

An implementation of the JSend specification in Rust.

See the crate documention, the examples, and the JSend specification for more information.

lib.rs:

The jsend crate provides an implementation of the JSend specification for API responses in Rust applications.

Usage

Add jsend to your Cargo.toml:

[dependencies]
jsend = "1.0"
serde = { version = "1.0", features = ["derive"] }

Basic Example

use jsend::JSendResponse;
use std::collections::HashMap;

// Success response with data
let data = Some(HashMap::from([("key", "value")]));
let response = JSendResponse::success(data);
println!("{}", serde_json::to_string(&response).unwrap());

// Error response
let error_response = JSendResponse::error("An error occurred".to_string(), Some(100), None::<String>);
println!("{}", serde_json::to_string(&error_response).unwrap());

A more in-depth example of how this crate could be used with a framework like axum can be found in the examples/ directory.

Features

• serde: Enabled by default. Adds serde::Serialize and serde::Deserialize derives, along with attributes to serialize into JSON according to the JSend specification.
