time-iso8601

以4位年格式和2位时间精度序列化和反序列化来自OffsetDateTime的timecrate，以便与大多数Web框架兼容。

示例

use serde::{Serialize, Deserialize};
use time::OffsetDateTime;

#[derive(Debug, Serialize, Deserialize)]
struct User {
    #[serde(with = "time-iso8601")]
    datetime_field: OffsetDateTime,
    #[serde(with = "time-iso8601::option")]
    optional_field: Option<OffsetDateTime>,
}
