Convert YAML to Rust online, free. YAML is an indentation-based superset of JSON favoured for human-edited config. Rust structs with serde derives serialize/deserialize data safely and fast. YAML to Rust conversion parses your YAML against the YAML 1.2.2 grammar (https://yaml.org/spec/1.2.2/), builds an in-memory model of its keys, nested objects and arrays, then emits ready-to-use Rust types with serde #[derive(Serialize, Deserialize)] attributes following the Serde conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include Rust services & CLIs, WASM modules and high-performance parsing.
It maps the full structure of your YAML onto idiomatic Rust types, following the Serde conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste YAML and generate Rust types from Rust immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested YAML objects, tables and arrays are mapped faithfully onto Rust, including nested types and optional fields.
Your YAML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
A YAML document and its Rust equivalent:
YAML input:
label: web
replicas: 3
exposed: falseOutput:
#[derive(Serialize, Deserialize)]
struct Service {
label: String,
replicas: i64,
exposed: bool,
}Paste your YAML into the editor and press "Convert to Rust". The tool parses it against the YAML 1.2.2 grammar, then generates Rust types following Serde conventions — instantly and entirely in your browser. You can validate or format the YAML first to be sure it is clean.
YAML anchors and aliases are expanded and comments are dropped before Rust is produced, and indentation defines the structure. Note that YAML 1.1 treats words like "yes" and "no" as booleans, so quote them if you want strings.
Optional or nullable members in the generated Rust are inferred from keys missing in some records of your YAML, following Serde. Include the optional fields in your sample so they are typed correctly.
YAML (YAML Ain't Markup Language) (YAML) — YAML is an indentation-based superset of JSON favoured for human-edited config. Rust structs (Rust) — Rust structs with serde derives serialize/deserialize data safely and fast. This converter maps the structure of your YAML onto Rust so you can use it for Rust services & CLIs.
Yes. Invalid YAML is flagged with a clear error before anything is converted. Common YAML problems to check are spaces (never tabs) for indentation, consistent indent levels, and no duplicate keys. Starting from clean input keeps the generated Rust accurate.
Yes. The entire YAML-to-Rust conversion runs locally in your browser in JavaScript — your YAML is never uploaded, logged or stored. That matters when the data is something like Kubernetes & Docker Compose manifests, which should not leave your machine.
The generated Rust is ready for Rust services & CLIs, WASM modules and high-performance parsing. Copy or download it and drop it straight into your codebase.
