Trait Deserialize

Source

pub trait Deserialize<'de>: Sized {
    // Required method
    fn deserialize<D>(
        deserializer: D,
    ) -> Result<Self, <D as Deserializer<'de>>::Error>
       where D: Deserializer<'de>;
}

Expand description

A data structure that can be deserialized from any data format supported by Serde.

Serde provides Deserialize implementations for many Rust primitive and standard library types. The complete list is here. 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.

§Lifetime

The 'de lifetime of this trait is the lifetime of data that may be borrowed by Self when deserialized. See the page Understanding deserializer lifetimes for a more detailed explanation of these lifetimes.

Required Methods§

Source

fn deserialize<D>( deserializer: D, ) -> Result<Self, <D as Deserializer<'de>>::Error>
where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

See the Implementing Deserialize section of the manual for more information about how to implement this method.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
