Struct u4

pub struct u4(/* private fields */);

An unsigned integer which contains 4 bits

Implementations

impl u4

pub const MAX: u8 = 15u8

The largest value that can be stored

pub const MIN: u8 = 0u8

The smallest value that can be stored

pub const unsafe fn new_unchecked(value: u8) -> Self

Create a new u4 from an inner value

This method does not do any checks that the value passed is valid. To check that, use the u4::new function.

Safety

The value must be valid value of the given type.

pub fn new(value: u8) -> Option<Self>

Create a new u4 from an inner value

This method checks that the inner value is valid, and return None if it isn’t.

pub const fn value(self) -> u8

Get the stored value
