锈色波斯日历

Rust Persian Calendar v0.1.1提供了波斯历（阳历回历）和公历之间转换的功能。儒略历用作所有转换的接口。 crate 名称为ptime ，它与 crate 时间兼容。此源代码已根据 MIT 许可证获得许可，可以在 LICENSE 文件中找到该许可证。

安装

将ptime = "0.1"添加到Cargo.toml的dependencies项部分：

[ dependencies ]
time = " 0.1 "
ptime = " 0.1 "

入门

1-导入包ptime 。大多数时候您还需要导入time箱。

 extern crate ptime ;
extern crate time ;

2-将公历转换为波斯历。

 let p_tm = ptime :: from_gregorian_date ( 2016 , 2 , 21 ) . unwrap ( ) ;

assert_eq ! ( p_tm.tm_year, 1395 ) ;
assert_eq ! ( p_tm.tm_mon, 0 ) ;
assert_eq ! ( p_tm.tm_mday, 2 ) ;

3-将波斯历转换为公历。

 let g_tm = ptime :: from_persian_date ( 1395 , 0 , 2 ) . unwrap ( ) . to_gregorian ( ) ;

assert_eq ! ( g_tm.tm_year, 2016 ) ;
assert_eq ! ( g_tm.tm_mon, 2 ) ;
assert_eq ! ( g_tm.tm_mday, 21 ) ;

4-获取当前时间。

 let p_tm = ptime :: now ( ) ;
println ! ( "Current time: {}" , p_tm ) ;

let p_tm_utc = ptime :: now_utc ( ) ;
println ! ( "Current time at UTC: {}" , p_tm_utc ) ;

5- 设置时间格式。

 let p_tm = ptime :: from_gregorian ( time :: now ( ) ) ;
println ! ( "{}" , p_tm.to_string ( "yyyy-MM-dd HH:mm:ss.ns" ) ) ;

///     yyyy, yyy, y     year (e.g. 1394)
///     yy               2-digits representation of year (e.g. 94)
///     MMM              the Persian name of month (e.g. فروردین)
///     MM               2-digits representation of month (e.g. 01)

///     A                the Persian name of 12-Hour marker (e.g. قبل از ظهر)

///     kk               2-digits representation of hour [01-24]
///     k                hour [1-24]
///     hh               2-digits representation of hour [01-12]
///     h                hour [1-12]
///     KK               2-digits representation of hour [00-11]
///     K                hour [0-11]
///     mm               2-digits representation of minute [00-59]
///     m                minute [0-59]
///     ss               2-digits representation of seconds [00-59]
///     s                seconds [0-59]
///     ns               nanoseconds
