parse string to std::time::Duration

Parse string to Duration . The String value unit support for one of:[y,mon,w,d,h,m,s] - y:Year. Support string value: ["y" | "year" | "Y" | "YEAR" | "Year"]. e.g. 1y - mon:Month.Support string value:["mon" | "MON" | "Month" | "month" | "MONTH"]. e.g. 1mon - w:Week.Support string value: ["w" | "W" | "Week" | "WEEK" | "week"]. e.g. 1w - d:Day.Support string value: ["d" | "D" | "Day" | "DAY" | "day"]. e.g. 1d - h:Hour.Support string value: ["h" | "H" | "Hour" | "HOUR" | "hour"]. e.g. 1h - m:Minute.Support string value: ["m" | "M" | "Minute" | "MINUTE" | "minute"]. e.g. 1m - m:Second.Support string value: ["s" | "S" | "Second" | "SECOND" | "second"]. e.g. 1s

Also,duration_str support time duration simple evaluation(+,*). See example:

example

toml [dependencies] duration-str = "0.2"

```rust use duration_str::parse; use std::time::Duration;

fn main() { let duration = parse("1d").unwrap(); assert_eq!(duration,Duration::new(246060,0));

let duration = parse("3m+31").unwrap();
assert_eq!(duration,Duration::new(211,0));

let duration = parse("3m + 31").unwrap();
assert_eq!(duration,Duration::new(211,0));

let duration = parse("1m*10").unwrap();
assert_eq!(duration,Duration::new(600,0));

let duration = parse("1m * 10").unwrap();
assert_eq!(duration,Duration::new(600,0));

} ```

deserialize in struct

deserialize to std::time::Duration

```rust use durationstr::deserializeduration; use serde::*; use std::time::Duration;

[derive(Debug, Deserialize)]

struct Config { #[serde(deserializewith = "deserializeduration")] time_ticker: Duration, }

fn main() { let json = r#"{"timeticker":"1m+30"}"#; let config: Config = serdejson::fromstr(json).unwrap(); asserteq!(config.time_ticker, Duration::new(60 + 30, 0)); } ```

Also you can use deserialize_duration_chrono function

```rust use chrono::Duration; use durationstr::deserializeduration_chrono; use serde::*;

[derive(Debug, Deserialize)]

struct Config { #[serde(deserializewith = "deserializedurationchrono")] timeticker: Duration, }

fn main() { let json = r#"{"timeticker":"1m+30"}"#; let config: Config = serdejson::fromstr(json).unwrap(); asserteq!(config.time_ticker, Duration::seconds(60 + 30)); } ```
