pub enum Meaning {
Whole(char),
LeadSurrogate(u16),
TrailSurrogate(u16),
Prefix(usize),
Suffix,
}Meaning of a complete or partial UTF-8 codepoint.
Not all checking is performed eagerly. That is, a codepoint Prefix or
Suffix may in reality have no valid completion.
Variants
Whole | We found a whole codepoint. |
LeadSurrogate | We found something that isn't a valid Unicode codepoint, but
it would correspond to a UTF-16 leading surrogate code unit,
i.e. a value in the range The argument is the code unit's 10-bit index within that range. These are found in UTF-8 variants such as CESU-8 and WTF-8. |
TrailSurrogate | We found something that isn't a valid Unicode codepoint, but
it would correspond to a UTF-16 trailing surrogate code unit,
i.e. a value in the range The argument is the code unit's 10-bit index within that range. These are found in UTF-8 variants such as CESU-8 and WTF-8. |
Prefix | We found only a prefix of a codepoint before the buffer ended. Includes the number of additional bytes needed. |
Suffix | We found only a suffix of a codepoint before running off the start of the buffer. Up to 3 more bytes may be needed. |
