Rust serde

Serde is a framework for ser ializing and de serializing Rust data structures efficiently and generically, rust serde. The Serde ecosystem consists of data structures that know how to rust serde 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.

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. This almost always means that you are using libraries that depend on incompatible versions of Serde. You may be depending on serde 1.

Rust serde

A data structure that can be serialized into any data format supported by Serde. Serde provides Serialize implementations for many Rust primitive and standard library types. The complete list is here. All of these can be serialized using Serde out of the box. See the derive section of the manual for how to use this. In rare cases it may be necessary to implement Serialize manually for some type in your program. See the Implementing Serialize section of the manual for more about this. Third-party crates may provide Serialize implementations for types that they expose. See the Implementing Serialize section of the manual for more information about how to implement this method. This impl requires the "rc" Cargo feature of Serde. Serializing a data structure containing Rc will serialize a copy of the contents of the Rc each time the Rc is referenced within the data structure. Serialization will not attempt to deduplicate these repeated data. Serializing a data structure containing Arc will serialize a copy of the contents of the Arc each time the Arc is referenced within the data structure. Owners dtolnay github:serde-rs:publish. Required Methods serialize Implementations on Foreign Types!

Folders and files Name Name Last commit message. Borrow data for this field from the deserializer by using zero-copy deserialization, rust serde. The "derive" feature is only required when using [derive Serialize, Deserialize ] to make Serde work with structs and enums defined in your crate.

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. You signed in with another tab or window. Reload to refresh your session.

It is more flexible and composable, but work with fewer types. You can specify converters for the inner types of a field, e. For example, the mime field from above could be nested in one or more data structures:. This means the field can still be missing during deserialization and will be filled with the value None. Then it becomes necessary to apply [serde default ] on the field in question.

A data structure that can be serialized into any data format supported by Serde. See this example. Serde is a framework for ser ializing and de serializing Rust data structures efficiently and generically.
