Struct u7

pub struct u7(/* private fields */);

A 7-bit integer type.

Wraps the u8 type and ensures that the top bit is always zero.

Implementations

impl u7

pub const fn max_value() -> u7

The maximum value that this restricted integer can hold.

pub const fn new(raw: u8) -> u7

Creates a restricted int from its non-restricted counterpart by masking off the extra bits.

pub const fn from_int_lossy(raw: u8) -> u7

Creates a restricted int from its non-restricted counterpart by masking off the extra bits.

pub fn try_from(raw: u8) -> Option<u7>

Returns Some if the raw integer is within range of the restricted integer, and None otherwise.

pub fn as_int(self) -> u8

Get the inner integer out of the wrapper. The inner integer is guaranteed to be in range of the restricted wrapper.

pub fn slice_try_from_int(raw: &[u8]) -> Option<&[u7]>

Cast a slice of raw integers to a slice of restricted integers, only if there are no out-of-range integers.

pub fn slice_from_int(raw: &[u8]) -> &[u7]

Cast a slice of raw integers to a slice of restricted integers.

The slice is truncated up to the first out-of-range integer, if there is any.

pub unsafe fn slice_from_int_unchecked(raw: &[u8]) -> &[u7]

Cast a slice of raw integers to a slice of restricted integers.

Safety

The input slice must not contain any out-of-range integers.

pub fn slice_try_from_int_mut(raw: &mut [u8]) -> Option<&mut [u7]>

Cast a slice of mutable raw integers to a slice of mutable restricted integers, only if there are no out-of-range integers.

pub fn slice_from_int_mut(raw: &mut [u8]) -> &mut [u7]

Cast a slice of mutable raw integers to a slice of mutable restricted integers.

The slice is truncated up to the first out-of-range integer, if there is any.

pub unsafe fn slice_from_int_unchecked_mut(raw: &mut [u8]) -> &mut [u7]

Cast a slice of mutable raw integers to a slice of mutable restricted integers.

Safety

The input slice must not contain any out-of-range integers.

pub fn slice_as_int(slice: &[u7]) -> &[u8]

Cast a slice of restricted integers to the corresponding raw integers.

All integers are guaranteed to be within range of the restricted int.
