DateTime 转 String String 转 DateTime DateTime 转 timestamp timestamp 转 DateTime 时区转换 时间计算 总结 在开发过程中,我们经常有对时间和日期处理的需求。不论是日历应用、日程安排、还是时间戳记录,准确的时间数据处理都是必不可少的。Rust 社区提供的 chrono 库以其强大的
你可以使用 NaiveDateTime::from_timestamp 方法将 Unix 时间戳转换为 NaiveDateTime 对象,然后可以使用 DateTime::from_utc 方法将其转换为 DateTime<Utc> 对象。 rust use chrono::{NaiveDateTime, DateTime, Utc}; fn timestamp_to_datetime(timestamp: u64) -> DateTime<Utc> { let nai...
