Trait rocket::serde::Serialize[][src]

pub trait Serialize {

    where
        S: Serializer
; }
Expand description

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.

Additionally, Serde provides a procedural macro called serde_derive to automatically generate Serialize 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 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. For example the linked-hash-map crate provides a LinkedHashMap<K, V> type that is serializable by Serde because the crate provides an implementation of Serialize for it.

Required methods

Serialize this value into the given Serde serializer.

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

use serde::ser::{Serialize, SerializeStruct, Serializer};

struct Person {
    name: String,
    age: u8,
    phones: Vec<String>,
}

// This is what #[derive(Serialize)] would generate.
impl Serialize for Person {
    fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>
    where
        S: Serializer,
    {
        let mut s = serializer.serialize_struct("Person", 3)?;
        s.serialize_field("name", &self.name)?;
        s.serialize_field("age", &self.age)?;
        s.serialize_field("phones", &self.phones)?;
        s.end()
    }
}

Implementations on Foreign Types

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.

This impl requires the "rc" Cargo feature of Serde.

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. Serialization will not attempt to deduplicate these repeated data.
