Implementations

impl LeadForTwoByte

pub const MIN: Self = Self::Bc2

Minimum possible value.

pub const MAX: Self = Self::Bdf

Maximum possible value.

pub const fn is(byte: u8) -> bool

Whether byte is in range for this type.

Safety-usable invariant

Iff this method returns true, the safety invariant of new_unchecked() is satisfied.

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

Unchecked constructor

Safety

lead must be in the range 0xC2 to 0xDF, inclusive.

Panics

When debug assertions are enabled, panics if the safety invariant is not upheld.

pub const fn try_new(byte: u8) -> Result<Self, Utf8ByteError>

Fallible constructor

Ok if in the range 0xC2 to 0xDF, inclusive, and Err otherwise.

pub const fn to_u8(self) -> u8

Convert to plain byte

pub const fn to_non_ascii(self) -> NonAscii

Convert to NonAscii

pub const fn to_lead_for_multi_byte(self) -> LeadForMultiByte

Convert to LeadForMultiByte

pub const fn low_five(self) -> u8

Obtain the least-significant five bits (i.e. the non-tag bits).

Safety-usable invariant

Only the least-significant five bits can have non-zero values.

pub const fn low_five_u32(self) -> u32

Obtain the least-significant five bits (i.e. the non-tag bits) as u32.

Safety-usable invariant

Only the least-significant five bits can have non-zero values.
