Struct Option 

pub struct Option<F>(/* private fields */);

Adapter for Option

Example

use serdapt as sa;
use serde::{Deserialize, Serialize};
use serde_json::json;

#[derive(Deserialize, Serialize)]
struct Foo(#[serde(with = "sa::Option::<sa::Str>")] Option<i32>);

let v = serde_json::to_value(Foo(Some(33))).unwrap();
assert_eq!(v, json!("33"));

Implementations

impl<F> Option<F>

pub fn serialize<T, S>(value: &T, serializer: S) -> Result<S::Ok, S::Error>

where T: ?Sized, S: Serializer, Self: SerializeWith<T>,

Serializes value with adapter

pub fn deserialize<'de, T, D>(deserializer: D) -> Result<T, D::Error>

where D: Deserializer<'de>, Self: DeserializeWith<'de, T>,
