pub enum HexLiteralKind {
    X,
    UnicodeShort,
    UnicodeLong,
}
Expand description

The type of a Unicode hex literal.

Note that all variants behave the same when used with brackets. They only differ when used without brackets in the number of hex digits that must follow.

Variants

X

A \x prefix. When used without brackets, this form is limited to two digits.

UnicodeShort

A \u prefix. When used without brackets, this form is limited to four digits.

UnicodeLong

A \U prefix. When used without brackets, this form is limited to eight digits.

Implementations
