Trait geng_core::prelude::Display

pub trait Display {
    fn fmt(&self, f: &mut Formatter) -> Result<(), Error>;
}

Format trait for an empty format, {}.

Display is similar to Debug, but Display is for user-facing output, and so cannot be derived.

For more information on formatters, see the module-level documentation.

Examples

Implementing Display on a type:

use std::fmt;

struct Point {
    x: i32,
    y: i32,
}

impl fmt::Display for Point {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        write!(f, "({}, {})", self.x, self.y)
    }
}

let origin = Point { x: 0, y: 0 };

assert_eq!(format!("The origin is: {}", origin), "The origin is: (0, 0)");

Required methods

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

Examples

use std::fmt;

struct Position {
    longitude: f32,
    latitude: f32,
}

impl fmt::Display for Position {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        write!(f, "({}, {})", self.longitude, self.latitude)
    }
}

assert_eq!("(1.987, 2.983)",
           format!("{}", Position { longitude: 1.987, latitude: 2.983, }));

impl Display for NaiveTime

The Display output of the naive time t is the same as t.format("%H:%M:%S%.f").

The string printed can be readily parsed via the parse method on str.

It should be noted that, for leap seconds not on the minute boundary, it may print a representation not distinguishable from non-leap seconds. This doesn't matter in practice, since such leap seconds never happened. (By the time of the first leap second on 1972-06-30, every time zone offset around the world has standardized to the 5-minute alignment.)

Example

use chrono::NaiveTime;

assert_eq!(format!("{}", NaiveTime::from_hms(23, 56, 4)),              "23:56:04");
assert_eq!(format!("{}", NaiveTime::from_hms_milli(23, 56, 4, 12)),    "23:56:04.012");
assert_eq!(format!("{}", NaiveTime::from_hms_micro(23, 56, 4, 1234)),  "23:56:04.001234");
assert_eq!(format!("{}", NaiveTime::from_hms_nano(23, 56, 4, 123456)), "23:56:04.000123456");

Leap seconds may also be used.

assert_eq!(format!("{}", NaiveTime::from_hms_milli(6, 59, 59, 1_500)), "06:59:60.500");

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

impl<Tz> Display for Date<Tz> where
    Tz: TimeZone,
    <Tz as TimeZone>::Offset: Display, 

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

impl Display for NaiveDate

The Display output of the naive date d is the same as d.format("%Y-%m-%d").

The string printed can be readily parsed via the parse method on str.

Example

use chrono::NaiveDate;

assert_eq!(format!("{}", NaiveDate::from_ymd(2015,  9,  5)), "2015-09-05");
assert_eq!(format!("{}", NaiveDate::from_ymd(   0,  1,  1)), "0000-01-01");
assert_eq!(format!("{}", NaiveDate::from_ymd(9999, 12, 31)), "9999-12-31");

ISO 8601 requires an explicit sign for years before 1 BCE or after 9999 CE.

assert_eq!(format!("{}", NaiveDate::from_ymd(   -1,  1,  1)),  "-0001-01-01");
assert_eq!(format!("{}", NaiveDate::from_ymd(10000, 12, 31)), "+10000-12-31");

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

impl Display for NaiveDateTime

The Debug output of the naive date and time dt is the same as dt.format("%Y-%m-%d %H:%M:%S%.f").

It should be noted that, for leap seconds not on the minute boundary, it may print a representation not distinguishable from non-leap seconds. This doesn't matter in practice, since such leap seconds never happened. (By the time of the first leap second on 1972-06-30, every time zone offset around the world has standardized to the 5-minute alignment.)

Example

use chrono::NaiveDate;

let dt = NaiveDate::from_ymd(2016, 11, 15).and_hms(7, 39, 24);
assert_eq!(format!("{}", dt), "2016-11-15 07:39:24");

Leap seconds may also be used.

let dt = NaiveDate::from_ymd(2015, 6, 30).and_hms_milli(23, 59, 59, 1_500);
assert_eq!(format!("{}", dt), "2015-06-30 23:59:60.500");
