Struct tea_dtype::TimeDelta

pub struct TimeDelta {
    pub months: i32,
    pub inner: TimeDelta,
}

Represents a duration of time with both months and a more precise duration.

This struct combines a number of months with a chrono::Duration to represent time intervals that may include calendar-specific units (months) as well as fixed-length durations.

Fields

• months: The number of months in the time delta.
• inner: A chrono::Duration representing the precise duration beyond whole months.

Serialization

When the “serde” feature is enabled, this struct can be serialized and deserialized.

Fields

months: i32

inner: TimeDelta

Implementations

impl TimeDelta

pub fn parse(duration: &str) -> Result<TimeDelta, TError>

Parse timedelta from string

for example: “2y1mo-3d5h-2m3s” Parses a string representation of a duration into a TimeDelta.

This function supports a variety of time units and can handle complex duration strings.

Supported Units

• ns: nanoseconds

• us: microseconds

• ms: milliseconds

• s: seconds

• m: minutes

• h: hours

• d: days

• w: weeks

• mo: months

• y: years

Format

The duration string should be in the format of <number><unit>, and multiple such pairs can be combined. For example: “2y1mo-3d5h-2m3s” represents 2 years, 1 month, minus 3 days, 5 hours, minus 2 minutes, and 3 seconds.

Arguments

• duration - A string slice that holds the duration to be parsed.

Returns

• TResult<Self> - A Result containing the parsed TimeDelta if successful, or an error if parsing fails.

Examples

use tea_time::TimeDelta;

let td = TimeDelta::parse("1y2mo3d4h5m6s").unwrap();
assert_eq!(td.months, 14); // 1 year and 2 months
assert_eq!(td.inner, chrono::Duration::seconds(3 * 86400 + 4 * 3600 + 5 * 60 + 6));
