Expand description

The common set of methods for time component.

Required Methods§

source

fn hour(&self) -> u32

Returns the hour number from 0 to 23.

source

fn minute(&self) -> u32

Returns the minute number from 0 to 59.

source

fn second(&self) -> u32

Returns the second number from 0 to 59.

source

fn nanosecond(&self) -> u32

Returns the number of nanoseconds since the whole non-leap second. The range from 1,000,000,000 to 1,999,999,999 represents the leap second.

source

fn with_hour(&self, hour: u32) -> Option<Self>

Makes a new value with the hour number changed.

Returns None when the resulting value would be invalid.

source

fn with_minute(&self, min: u32) -> Option<Self>

Makes a new value with the minute number changed.

Returns None when the resulting value would be invalid.

source

fn with_second(&self, sec: u32) -> Option<Self>

Makes a new value with the second number changed.

Returns None when the resulting value would be invalid. As with the second method, the input range is restricted to 0 through 59.

source

fn with_nanosecond(&self, nano: u32) -> Option<Self>

Makes a new value with nanoseconds since the whole non-leap second changed.

Returns None when the resulting value would be invalid. As with the nanosecond method, the input range can exceed 1,000,000,000 for leap seconds.

Provided Methods§

source

fn hour12(&self) -> (bool, u32)

Returns the hour number from 1 to 12 with a boolean flag, which is false for AM and true for PM.

source

fn num_seconds_from_midnight(&self) -> u32

Returns the number of non-leap seconds past the last midnight.

Every value in 00:00:00-23:59:59 maps to an integer in 0-86399.

This method is not intended to provide the real number of seconds since midnight on a given day. It does not take things like DST transitions into account.
