Crate readable

Expand description

Human readable data formatting.

This crate turns various data into human-readable strings.

Most of the internal strings are implemented as fixed length, stack allocated arrays that are Copy-able.

Feature flags

FlagPurpose
serdeEnables serde on all types
ignore_nan_infDisables checking f64’s for f64::NAN, f64::INFINITY, and f64::NEG_INFINITY
inline_dateInlines any Date that is in YYYY-MM-HH format and is between year 1900-2100
inline_timeInlines any Time that is under 1 hour, 1 minute (0..=3660)
inline_runtimeInlines ALL of Runtime (0:00..99:59:59/0..=359999)
fullEnables everything above

Warning: The inline_* features are disabled by default. While they increase speed, they also heavily increase build time and binary size.

Unsigned integers:

let a = readable::Unsigned::from(1000_u64);

assert!(a == 1000_u64);
assert!(a == "1,000");

Signed integers:

let a = readable::Int::from(-1000);

assert!(a == -1000);
assert!(a == "-1,000");

Floats:

let a = readable::Float::from(1000.123);

assert!(a == 1000.123);
assert!(a == "1,000.123");

Percents:

let a = readable::Percent::from(1000.123);

assert!(a == 1000.123);
assert!(a == "1,000.12%");

Runtime:

let a = readable::Runtime::from(11111_u16);

assert!(a == 11111);
assert!(a == "3:05:11");

Time:

let a = readable::Time::from(86399_u64);

assert!(a == 86399_u64);
assert!(a == "23 hours, 59 minutes, 59 seconds");

Date:

let a = readable::Date::from_str("2014-12-31").unwrap();

assert!(a == (2014, 12, 31));
assert!(a == "2014-12-31");

Comparison

All types implement Display, PartialEq, PartialEq<&str> and PartialEq for their inner number primitive.

Example 1:

let a = std::time::Duration::from_secs(86399);
let b = readable::Time::from(a);

assert!(b == "23 hours, 59 minutes, 59 seconds");

This is comparing b’s inner String.

Example 2:

let a = readable::Int::from(-1000);

assert!(a == -1000);

This is comparing a’s inner i64.

Example 3:

let a = readable::Unsigned::from(1000_u64);
let b = readable::Unsigned::from(1000_u64);

assert!(a == b);

This compares both the u64 AND String inside a and b.
