In crates that derive an implementation of `Serialize` or `Deserialize`, you
|
||||
must depend on the [`serde`] crate, not `serde_core`.

**Serde is a framework for *ser*ializing and *de*serializing Rust data structures efficiently and generically.**
|

In crates that handwrite implementations of Serde traits, or only use them as
|
||||
trait bounds, depending on `serde_core` is permitted. But `serde` re-exports all
|
||||
of these traits and can be used for this use case too. If in doubt, disregard
|
||||
`serde_core` and always use `serde`.

Serde Core exposes core traits and utilities for interacting with Serde's data model.
|

It is intended to be consumed by Serde's data formats and other crates that implement the Serde traits by hand.

|

If you are looking to use Serde in your library/application to simply serialize and deserialize data, you most likely want to use [Serde](https://crates.io/crates/serde) directly.

Serde Core does _not_ offer any convenience functions for automatically implementing `Serialize` or `Deserialize` via a `#[derive]` macro.

//! # Serde Core
|
||||
//!
|
||||
//! Serde is a framework for ***ser***ializing and ***de***serializing Rust data
|
||||
//! structures efficiently and generically.
|
||||
//!
|
||||
//! `serde_core` provides essential traits and functions that form the backbone of Serde. It is intended for use by data format implementations;
|
||||
//! while it is possible to depend on `serde` crate in a crate that implements a data format,
|
||||
//! doing so means that the build of data format crate cannot start until serde_derive is done building (if that feature is enabled).
|
||||
//! Thus, implementing a data format in terms of serde_core and not of serde should improve compile times of users of your data format.
|
||||
//! The `serde_core` crate contains Serde's trait definitions with **no support
|
||||
//! for #\[derive()\]**.
|
||||
//!
|
||||
//! Alternatively, as an user of data formats you could use `serde_core` instead of `serde` if you do not intend to enable derive feature on `serde`.
|
||||
//! In crates that derive an implementation of `Serialize` or `Deserialize`, you
|
||||
//! must depend on the [`serde`] crate, not `serde_core`.
|
||||
//!
|
||||
//! If you're still unsure which crate to use, favor `serde` for the most straightforward experience.
|
||||
//! For more detailed information and usage examples, refer to Serde's documentation at <https://serde.rs/>.
|
||||
//! In crates that handwrite implementations of Serde traits, or only use them
|
||||
//! as trait bounds, depending on `serde_core` is permitted. But `serde`
|
||||
//! re-exports all of these traits and can be used for this use case too. If in
|
