Type Definition dactyl::NiceU16

pub type NiceU16 = NiceWrapper<SIZE>;

NiceU16 provides a quick way to convert a u16 into a formatted byte string for e.g. printing. Commas are added for every thousand.

That’s it!

Examples

use dactyl::NiceU16;
assert_eq!(
    NiceU16::from(33231).as_str(),
    "33,231"
);

Traits

Rustdoc doesn’t do a good job at documenting type alias implementations, but NiceU16 has a bunch, including:

• AsRef<[u8]>
• AsRef<str>
• Borrow<[u8]>
• Borrow<str>
• Clone
• Copy
• Default
• Deref<Target=[u8]>
• Display
• Eq / PartialEq
• Hash
• Ord / PartialOrd

You can instantiate a NiceU16 with:

• From<u16>
• From<Option<u16>>
• From<NonZeroU16>
• From<Option<NonZeroU16>>

When converting from a None, the result will be equivalent to zero.

Implementations

impl NiceU16

pub fn with_separator(num: u16, sep: u8) -> Self

New Instance w/ Custom Separator.

Create a new instance, defining any arbitrary ASCII byte as the thousands separator.

If you’re good with commas, just use [NiceU16::from] instead.

Examples

use dactyl::NiceU16;

let num = NiceU16::from(31415_u16);
assert_eq!(num.as_str(), "31,415");

let num = NiceU16::with_separator(31415_u16, b'_');
assert_eq!(num.as_str(), "31_415");

Panics

This method will panic if the separator is invalid ASCII.
