mod.rs	Generic data structure deserialization framework. The two most important traits in this module are [`Deserialize`] and [`Deserializer`]. - A type that implements `Deserialize` is a data structure that can be deserialized from any data format supported by Serde, and conversely - A type that implements `Deserializer` is a data format that can deserialize any data structure supported by Serde. # The Deserialize trait Serde provides [`Deserialize`] implementations for many Rust primitive and standard library types. The complete list is below. All of these can be deserialized using Serde out of the box. Additionally, Serde provides a procedural macro called [`serde_derive`] to automatically generate [`Deserialize`] implementations for structs and enums in your program. See the [derive section of the manual] for how to use this. In rare cases it may be necessary to implement [`Deserialize`] manually for some type in your program. See the [Implementing `Deserialize`] section of the manual for more about this. Third-party crates may provide [`Deserialize`] implementations for types that they expose. For example the [`linked-hash-map`] crate provides a [`LinkedHashMap<K, V>`] type that is deserializable by Serde because the crate provides an implementation of [`Deserialize`] for it. # The Deserializer trait [`Deserializer`] implementations are provided by third-party crates, for example [`serde_json`], [`serde_yaml`] and [`postcard`]. A partial list of well-maintained formats is given on the [Serde website][data formats]. # Implementations of Deserialize provided by Serde This is a slightly different set of types than what is supported for serialization. Some types can be serialized by Serde but not deserialized. One example is `OsStr`. - Primitive types: - bool - i8, i16, i32, i64, i128, isize - u8, u16, u32, u64, u128, usize - f32, f64 - char - Compound types: - \[T; 0\] through \[T; 32\] - tuples up to size 16 - Common standard library types: - String - Option\<T\> - Result\<T, E\> - PhantomData\<T\> - Wrapper types: - Box\<T\> - Box\<\[T\]\> - Box\<str\> - Cow\<'a, T\> - Cell\<T\> - RefCell\<T\> - Mutex\<T\> - RwLock\<T\> - Rc\<T\>&emsp;(if features = \["rc"\] is enabled) - Arc\<T\>&emsp;(if features = \["rc"\] is enabled) - Collection types: - BTreeMap\<K, V\> - BTreeSet\<T\> - BinaryHeap\<T\> - HashMap\<K, V, H\> - HashSet\<T, H\> - LinkedList\<T\> - VecDeque\<T\> - Vec\<T\> - Zero-copy types: - &str - &\[u8\] - FFI types: - CString - Box\<CStr\> - OsString - Miscellaneous standard library types: - Duration - SystemTime - Path - PathBuf - Range\<T\> - RangeInclusive\<T\> - Bound\<T\> - num::NonZero* - `!` (unstable) - Net types: - IpAddr - Ipv4Addr - Ipv6Addr - SocketAddr - SocketAddrV4 - SocketAddrV6 [Implementing `Deserialize`]: https://serde.rs/impl-deserialize.html [`Deserialize`]: crate::Deserialize [`Deserializer`]: crate::Deserializer [`LinkedHashMap<K, V>`]: https://docs.rs/linked-hash-map/*/linked_hash_map/struct.LinkedHashMap.html [`postcard`]: https://github.com/jamesmunns/postcard [`linked-hash-map`]: https://crates.io/crates/linked-hash-map [`serde_derive`]: https://crates.io/crates/serde_derive [`serde_json`]: https://github.com/serde-rs/json [`serde_yaml`]: https://github.com/dtolnay/serde-yaml [derive section of the manual]: https://serde.rs/derive.html [data formats]: https://serde.rs/#data-formats	83879	55 %
