Struct IfIsHumanReadable

source
pub struct IfIsHumanReadable<H, F = Same>(/* private fields */);
Expand description

Use the first format if De/Serializer::is_human_readable, otherwise use the second

If the second format is not specified, the normal Deserialize/Serialize traits are used.

§Examples

use std::time::Duration;

#[serde_as]
#[derive(Deserialize, Serialize)]
struct A {
    #[serde_as(as = "IfIsHumanReadable<DisplayFromStr>")]
    number: u32,
}
let x = A {
    number: 777,
};
assert_eq!(json!({ "number": "777" }), serde_json::to_value(&x).unwrap());
assert_eq!(vec![145, 205, 3, 9], rmp_serde::to_vec(&x).unwrap());

#[serde_as]
#[derive(Deserialize, Serialize)]
struct B {
    #[serde_as(as = "IfIsHumanReadable<DurationMilliSeconds, DurationSeconds>")]
    duration: Duration,
}
let x = B {
    duration: Duration::from_millis(1500),
};
assert_eq!(json!({ "duration": 1500 }), serde_json::to_value(&x).unwrap());
assert_eq!(vec![145, 2], rmp_serde::to_vec(&x).unwrap());
