Struct PreparedTwoBytes 

pub struct PreparedTwoBytes { /* private fields */ }

Wrapper for the first two bytes and a precomputed value.

Implementations

impl PreparedTwoBytes

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

Constructor

first and second represent the first two bytes of a potential UTF-8 sequence for efficient checking for whether they actually form such a prefix.

pub const fn sequence_prefix(self) -> bool

true iff the two bytes form a prefix of a well-formed multi-byte UTF-8 sequence.

Safety-usable invariant

Callers may depend on the above for safety.
