Struct PreparedThreeBytes 

pub struct PreparedThreeBytes { /* private fields */ }

Wrapper for the first three bytes and a precomputed value.

Implementations

impl PreparedThreeBytes

pub const fn new(first: u8, second: u8, third: u8) -> Self

Constructor

first, second, and third represent the first three bytes of a potential UTF-8 sequence for efficient checking for whether they actually form a prefix of a well-formed UTF-8 sequence.

pub const fn new_with_prepared(prepared: PreparedTwoBytes, third: u8) -> Self

Constructor with already-prepared first two bytes

prepared and third represent the first three bytes of a potential UTF-8 sequence for efficient checking for whether they actually form a prefix of a well-formed UTF-8 sequence.

pub const fn prefix_of_four_byte(self) -> bool

Return true iff these three bytes represent a three-byte prefix of a well-formed four-byte UTF-8 sequence.

Safety-usable invariant

The caller may rely on the result for safety.
