Enum MixedUnit

Source
pub enum MixedUnit {
    Char(char),
    HighByte(u8),
}
Expand description

Used for mixed utf8 string literals, i.e. those that allow both unicode chars and high bytes.

Variants§

§

Char(char)

Used for ASCII chars (written directly or via \x00..\x7f escapes) and Unicode chars (written directly or via \u escapes).

For example, if ‘¥’ appears in a string it is represented here as MixedUnit::Char('¥'), and it will be appended to the relevant byte string as the two-byte UTF-8 sequence [0xc2, 0xa5]

§

HighByte(u8)

Used for high bytes (\x80..\xff).

For example, if \xa5 appears in a string it is represented here as MixedUnit::HighByte(0xa5), and it will be appended to the relevant byte string as the single byte 0xa5.
