Type Definition dactyl::NiceU8

source ·

pub type NiceU8 = NiceWrapper<SIZE>;

Expand description

NiceU8 provides a quick way to convert a u8 into a formatted byte string for e.g. printing.

That’s it!

Examples

use dactyl::NiceU8;
assert_eq!(
    NiceU8::from(231).as_str(),
    "231"
);

Traits

Rustdoc doesn’t do a good job at documenting type alias implementations, but NiceU8 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 NiceU8 with:

From<u8>
From<Option<u8>>
From<NonZeroU8>
From<Option<NonZeroU8>>

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

Implementations§

source §

This method will return return a byte slice that is at least two bytes long, left padding the value with a zero if its natural length is shorter. (In other words, this has no effect if the value is >= 10.)

Examples

assert_eq!(dactyl::NiceU8::from(3).as_bytes2(), b"03");
assert_eq!(dactyl::NiceU8::from(50).as_bytes2(), b"50");
assert_eq!(dactyl::NiceU8::from(113).as_bytes2(), b"113");

source

pub const fn as_bytes3(&self) -> &[u8] ⓘ

Triple Digit Bytes.

This method will return return a byte slice that is at least three bytes long, left padding the value with a zero if its natural length is shorter. (In other words, this has no effect if the value is >= 100.)

Examples

assert_eq!(dactyl::NiceU8::from(3).as_bytes3(), b"003");
assert_eq!(dactyl::NiceU8::from(50).as_bytes3(), b"050");
assert_eq!(dactyl::NiceU8::from(113).as_bytes3(), b"113");

source

pub fn as_str2(&self) -> &str

Double Digit Str.

This method will return return a string slice that is at least two chars long, left padding the value with a zero if its natural length is shorter. (In other words, this has no effect if the value is >= 10.)

Examples

assert_eq!(dactyl::NiceU8::from(3).as_str2(), "03");
assert_eq!(dactyl::NiceU8::from(50).as_str2(), "50");
assert_eq!(dactyl::NiceU8::from(113).as_str2(), "113");

source

pub const fn as_str3(&self) -> &str

Triple Digit Str.

This method will return return a string slice that is at least three chars long, left padding the value with zeroes if its natural length is shorter. (In other words, this has no effect if the value is >= 100.)

Examples

assert_eq!(dactyl::NiceU8::from(3).as_str3(), "003");
assert_eq!(dactyl::NiceU8::from(50).as_str3(), "050");
assert_eq!(dactyl::NiceU8::from(113).as_str3(), "113");
