Enum Encoding 

pub enum Encoding {
    Plain,
    Wide,
    Utf8,
    Utf16,
    Utf32,
}

The encoding prefix of a character constant or a string literal.

Variants

Plain

No prefix, whose element is a char.

Wide

L, whose element is a wchar_t and so is a fact about the target.

Utf8

u8, whose element is a char8_t, which is an unsigned char.

Utf16

u, whose element is a char16_t, which is a uint_least16_t.

Utf32

U, whose element is a char32_t, which is a uint_least32_t.

Implementations

impl Encoding

pub fn element_width(self, target: &TargetInfo) -> u32

The width of one element in bits.

pub fn is_signed(self, target: &TargetInfo) -> bool

Whether the element type is signed, which only char and wchar_t can be.

pub const fn prefix(self) -> &'static str

The prefix this encoding is written with, which is empty for a plain literal.

pub fn read_prefix(text: &str) -> Encoding

The prefix a spelling was written with, for a caller that needs the encoding of a literal it could not convert.
