Represents UTF-8 byte type based on the most significant bits the given byte

Examples

use utf8_rune::ByteType;

assert_eq!(f0, ByteType::FourOrMore(0xF0));
assert_eq!(f0.len(), 4);
assert_eq!(f0.is_ascii(), false);
assert_eq!(f0.is_continuation(), false);

use utf8_rune::ByteType;
let e4 = ByteType::from(0xE4u8);

assert_eq!(e4.len(), 3);
assert_eq!(e4.is_ascii(), false);
assert_eq!(e4.is_continuation(), false);

Trait Implementations

impl Clone for ByteType

fn clone(&self) -> ByteType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ByteType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&u8> for ByteType

fn from(byte: &u8) -> ByteType

Converts to this type from the input type.

impl From<u16> for ByteType

fn from(bytes: u16) -> ByteType

Converts to this type from the input type.

impl From<u32> for ByteType

fn from(bytes: u32) -> ByteType

Converts to this type from the input type.

impl From<u64> for ByteType

fn from(bytes: u64) -> ByteType

Converts to this type from the input type.

impl From<u8> for ByteType

fn from(byte: u8) -> ByteType

Converts to this type from the input type.

impl From<usize> for ByteType

fn from(bytes: usize) -> ByteType

Converts to this type from the input type.

impl PartialEq for ByteType

fn eq(&self, other: &ByteType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for ByteType
