serde-yaml

YAML serialization for Rust's serde framework.

Overview

serde-yaml is the standard YAML library for Rust applications. Built on the powerful serde serialization framework, it provides type-safe YAML processing for Rust's growing ecosystem.

About This Fork

This is a fork of the original serde-yaml by David Tolnay, which has been archived. The YAML Company maintains this fork with the author's approval to ensure continued support for the Rust ecosystem.

Why serde-yaml Matters

Powers Rust Applications

serde-yaml is used by Rust applications for:

  • Configuration Files - Type-safe config management
  • Data Serialization - Converting Rust structs to/from YAML
  • API Responses - YAML-based web APIs
  • Build Systems - Cargo and build configuration
  • CLI Tools - Command-line applications written in Rust

Growing Adoption

  • 20M+ downloads on crates.io
  • Standard choice for YAML in Rust
  • Part of the serde ecosystem
  • Used by major Rust projects

Type-Safe YAML

  • Compile-time type checking
  • Zero-cost abstractions
  • Memory safety guarantees
  • Rust's ownership model

Type Safety Benefits

serde-yaml provides compile-time guarantees:

// This won't compile if the YAML structure doesn't match
let config: Config = serde_yaml::from_str(yaml)?;

// Fields are guaranteed to exist
println!("Host: {}", config.database.host);

// Types are checked at compile time
let port: u16 = config.database.port;  // Can't accidentally be a string

Support serde-yaml

serde-yaml is maintained through the YES Program. YES members get:

  • Priority support for serde-yaml issues
  • Early notification of security vulnerabilities
  • Influence over roadmap and feature development
  • Direct access to maintainers
