Enum rustc_lexer::unescape::MixedUnit

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

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.

Trait Implementations

impl From<char> for MixedUnit

fn from(c: char) -> Self

Converts to this type from the input type.

impl From<u8> for MixedUnit

fn from(n: u8) -> Self

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.

Size: 8 bytes

Size for each variant:

• Char: 7 bytes
• HighByte: 1 byte
