|

A Rust crate for parsing human-readable relative time strings and human-readable datetime strings and converting them to a jiff's `Zoned` object.
|
||||
A Rust crate for parsing human-readable relative time strings and converting them to a `Duration`.
|
||||
|
||||
## Features
|
||||
|
||||
- Parses a variety of human-readable and standard time formats.
|
||||
- Parses a variety of human-readable time formats.
|
||||
- Supports positive and negative durations.
|
||||
- Allows for chaining time units (e.g., "1 hour 2 minutes" or "2 days 2 hours ago").
|
||||
- Allows for chaining time units (e.g., "1 hour 2 minutes" or "2 days and 2 hours").
|
||||
- Calculate durations relative to a specified date.
|
||||
- Relies on Jiff
|
||||
|
||||
## Usage
|
||||
|
||||
Add `parse_datetime` to your `Cargo.toml` with:
|
||||
Add this to your `Cargo.toml`:
|
||||
|
||||
```
|
||||
cargo add parse_datetime
|
||||
```toml
|
||||
[dependencies]
|
||||
humantime_to_duration = "0.2.1"
|
||||
```
|
||||
|
||||
Then, import the crate and use the `parse_datetime_at_date` function:
|
||||
Then, import the crate and use the `from_str` and `from_str_at_date` functions:
|
||||
```
|
||||
use humantime_to_duration::{from_str, from_str_at_date};
|
||||
use time::Duration;
|
||||
|
||||
```rs
|
||||
use jiff::{ToSpan, Zoned};

||||

|
||||
let now = Zoned::now();
|
||||
let after = parse_datetime_at_date(now.clone(), "+3 days");
|
||||
let duration = from_str("+3 days");
|
||||
assert_eq!(duration.unwrap(), Duration::days(3));
|
||||
|
||||
let today = OffsetDateTime::now_utc().date();
|
||||
let yesterday = today - Duration::days(1);
|
||||
assert_eq!(
|
||||
now.checked_add(3.days()).unwrap(),
|
||||
after.unwrap()
|
||||
from_str_at_date(yesterday, "2 days").unwrap(),
|
||||
Duration::days(1)
|
||||
);
|
||||
```
|
||||
|
||||
For DateTime parsing, import the `parse_datetime` function:
|
||||
|
||||
```rs
|
||||
use jiff::{civil::{date, time} ,Zoned};
|
||||
use parse_datetime::parse_datetime;
|
||||
|
||||
let dt = parse_datetime("2021-02-14 06:37:47");
|
||||
assert_eq!(dt.unwrap(), Zoned::now().with().date(date(2021, 2, 14)).time(time(6, 37, 47, 0)).build().unwrap());
|
||||
```
|
||||
|
||||
### Supported Formats

||||
|
||||
The `parse_datetime` and `parse_datetime_at_date` functions support absolute datetime and the following relative times:
|
||||
The `from_str` and `from_str_at_date` functions support the following formats for relative time:
|

||||
- use "next" or "last" with `unit` (e.g., "next week", "last year")
|
||||
- unix timestamps (for example "@0" "@1344000")
|
||||
- combined units with "and" or "," (e.g., "2 years and 1 month", "1 day, 2 hours" or "2 weeks 1 second")
|
||||
|
||||
`num` can be a positive or negative integer.
|
||||
`unit` can be one of the following: "fortnight", "week", "day", "hour", "minute", "min", "second", "sec" and their plural forms.
|
||||
|
||||
## Return Values
|
||||
|
||||
### parse_datetime and parse_datetime_at_date
|
||||
The `from_str` and `from_str_at_date` functions return:
|
||||
|
||||
The `parse_datetime` and `parse_datetime_at_date` function return:
|
||||
- `Ok(Duration)` - If the input string can be parsed as a relative time
|
||||
- `Err(ParseDurationError)` - If the input string cannot be parsed as a relative time
|
||||
|
||||
- `Ok(Zoned)` - If the input string can be parsed as a `Zoned` object
|
||||
- `Err(ParseDateTimeError::InvalidInput)` - If the input string cannot be parsed
|
||||
This function will return `Err(ParseDurationError::InvalidInput)` if the input string
|
||||
cannot be parsed as a relative time.
|
||||
|
||||
## Fuzzer

|
||||
$ cargo +nightly fuzz run fuzz_parse_datetime
|
||||
$ cargo fuzz run fuzz_from_str
|
||||
```
