[![CodeCov](https://codecov.io/gh/uutils/humantime_to_duration/branch/main/graph/badge.svg)](https://codecov.io/gh/uutils/humantime_to_duration)
A Rust crate for parsing human-readable relative time strings and human-readable datetime strings and converting them to a `DateTime`.
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 and 2 hours").
- Calculate durations relative to a specified date.
- Relies on Chrono
## Usage
@@ -20,37 +19,28 @@ Add this to your `Cargo.toml`:
```toml
[dependencies]
parse_datetime = "0.6.0"
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 chrono::{Duration, Local};
use parse_datetime::parse_datetime_at_date;
let now = Local::now();
let after = parse_datetime_at_date(now, "+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 + Duration::days(3)).naive_utc(),
after.unwrap().naive_utc()
from_str_at_date(yesterday, "2 days").unwrap(),
Duration::days(1)
);
```
For DateTime parsing, import the `parse_datetime` function:
```rs
use parse_datetime::parse_datetime;
use chrono::{Local, TimeZone};
let dt = parse_datetime("2021-02-14 06:37:47");
assert_eq!(dt.unwrap(), Local.with_ymd_and_hms(2021, 2, 14, 6, 37, 47).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:
- `num` `unit` (e.g., "-1 hour", "+3 days")
- `unit` (e.g., "hour", "day")
@@ -58,37 +48,28 @@ The `parse_datetime` and `parse_datetime_at_date` functions support absolute dat
- "yesterday"
- "tomorrow"
- use "ago" for the past
- use "next" or "last" with `unit` (e.g., "next week", "last year")
- combined units with "and" or "," (e.g., "2 years and 1 month", "1 day, 2 hours" or "2 weeks 1 second")
- unix timestamps (for example "@0" "@1344000")
`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(DateTime<FixedOffset>)` - If the input string can be parsed as a datetime
- `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
To run the fuzzer:
```
$ cd fuzz
$ cargo install cargo-fuzz
$ cargo +nightly fuzz run fuzz_parse_datetime
$ cargo fuzz run fuzz_from_str
```
