Function default_i16

pub const fn default_i16<const V: i16>() -> i16

Allows compact setting i16 field default value.

Example

use serde_aux::prelude::*;

#[derive(serde::Deserialize, Debug)]
struct MyStruct {
    #[serde(default = "default_i16::<-30>")]
    default_30: i16,
    #[serde(default)]
    default_zero: i16,
}

let s = r#"{}"#;
let a: MyStruct = serde_json::from_str(s).unwrap();
assert_eq!(a.default_30, -30);
assert_eq!(a.default_zero, 0);
