Rust serde

Serde is a framework for ser ializing and rust serde serializing Rust data structures efficiently and generically, rust serde. The Serde ecosystem consists of data structures that know how to serialize and deserialize themselves along with data formats that know how to serialize and deserialize other things.

Serde provides a derive macro to generate implementations of the Serialize and Deserialize traits for data structures defined in your crate, allowing them to be represented conveniently in all of Serde's data formats. You only need to set this up if your code is using [derive Serialize, Deserialize ]. This functionality is based on Rust's [derive] mechanism, just like what you would use to automatically derive implementations of the built-in Clone , Copy , Debug , or other traits. It is able to generate implementations for most structs and enums including ones with elaborate generic types or trait bounds. On rare occasions, for an especially convoluted type you may need to implement the traits manually.

Serde is a framework for ser ializing and de serializing Rust data structures efficiently and generically. Serde is one of the most widely used Rust libraries so any place that Rustaceans congregate will be able to help you out. It's acceptable to file a support issue in this repo but they tend not to get as many eyes as any of the above and may get closed without a response after some time. Skip to content.

Serialize and deserialize this field with the given name instead of its Rust name. This is useful for serializing fields as camelCase or serializing fields with names that are reserved Rust keywords. Deserialize this field from the given name or from its Rust name. May be repeated to specify multiple possible names for the same field. If the value is not present when deserializing, call a function to get a default value. This removes one level of structure between the serialized representation and the Rust data structure representation. It can be used for factoring common keys into a shared structure, or for capturing remaining fields into a map with arbitrary string keys.

Serde is a framework for ser ializing and de serializing Rust data structures efficiently and generically. The Serde ecosystem consists of data structures that know how to serialize and deserialize themselves along with data formats that know how to serialize and deserialize other things. Serde provides the layer by which these two groups interact with each other, allowing any supported data structure to be serialized and deserialized using any supported data format. Where many other languages rely on runtime reflection for serializing data, Serde is instead built on Rust's powerful trait system. A data structure that knows how to serialize and deserialize itself is one that implements Serde's Serialize and Deserialize traits or uses Serde's derive attribute to automatically generate implementations at compile time. This avoids any overhead of reflection or runtime type information. In fact in many situations the interaction between data structure and data format can be completely optimized away by the Rust compiler, leaving Serde serialization to perform the same speed as a handwritten serializer for the specific selection of data structure and data format. The following is a partial list of data formats that have been implemented for Serde by the community. Out of the box, Serde is able to serialize and deserialize common Rust data types in any of the above formats. In addition, Serde provides a derive macro to generate serialization implementations for structs in your own program.

The complete list is here. You may be depending on serde 1. Starlark , the format used for describing build targets by the Bazel and Buck build systems. Available on crate features std or alloc only. URL query strings, in the x-www-form-urlencoded format. Helper macro when implementing the Deserializer part of a new data format for Serde. It is able to generate implementations for most structs and enums including ones with elaborate generic types or trait bounds. A data structure that can be serialized into any data format supported by Serde. Serialize this field using a function that is different from its implementation of Serialize. This almost always means that you are using libraries that depend on incompatible versions of Serde. This impl requires the "rc" Cargo feature of Serde. In rare cases it may be necessary to implement Serialize manually for some type in your program. Field attributes.

Some common use cases are:. Check out the user guide to find out more tips and tricks about this crate.

This avoids any overhead of reflection or runtime type information.
